Magnetism is one of the most captivating physics concepts for young children because its effects are immediately visible and seemingly magical. Objects attract and repel without touching, compass needles swing to point north, and iron filings arrange themselves in invisible field patterns. But moving from fascination to understanding requires tools that make invisible magnetic fields visible. The best magnet apps use simulations and augmented reality to show field lines, demonstrate attraction and repulsion, and connect magnetism to electricity, navigation, and everyday technology.
How We Evaluated
Each app was tested by children aged five through twelve over a three-week period. We assessed conceptual understanding through hands-on demonstrations with real magnets before and after app use. We scored on five criteria:
- Scientific accuracy — Does the app correctly represent magnetic poles, field lines, and material properties?
- Visualization — Does the app make invisible magnetic fields visible and intuitive?
- Interactivity — Can children experiment with virtual magnets, change variables, and observe outcomes?
- Conceptual depth — Does the app connect magnetism to electromagnetism, compasses, and real-world applications?
- Value — Is the content worth the price?

Detailed Reviews
PhET Magnet & Compass — Best Field Visualization
PhET’s magnet and compass simulation, developed by the University of Colorado, is the gold standard for visualizing magnetic fields. Children place a bar magnet on screen and observe field lines radiating from the poles. A virtual compass needle responds to the field in real time as children drag it around the magnet. Flipping the magnet reverses the field, and bringing two magnets together demonstrates attraction and repulsion based on pole alignment.
An electromagnet module lets children wrap wire around a nail, connect a battery, and observe how current creates a magnetic field. Adjusting the number of wire coils and battery voltage changes the field strength, teaching the relationship between electricity and magnetism.
Why parents love it: PhET simulations are developed by physics educators and tested with students for conceptual accuracy. The field line visualization makes the invisible visible in a way that even physical iron filings cannot match because children can observe the field from any angle and in real time.
Limitation: The interface is functional rather than visually appealing to younger children. The simulation works best with brief parental setup and guided exploration.
Science Journal — Best Real Magnetometer
Science Journal (originally by Google, now maintained by Arduino Education) turns a smartphone’s magnetometer sensor into a real scientific instrument. Children move the phone near magnets, metal objects, speakers, and electronics to measure magnetic field strength in microteslas. A real-time graph shows field intensity as the phone moves, and children can record experiments, add notes, and compare measurements.
The power of this app is that it measures real magnetic fields from real objects. Children discover that refrigerator magnets have surprisingly weak fields, that speaker magnets are powerful, and that running electrical appliances produce detectable magnetic fields.
Why parents love it: Turning the phone into a magnetometer makes invisible fields tangible through real measurements. Children conduct genuine scientific experiments with a real instrument, building skills that transfer to laboratory science.
Limitation: The raw data display can be overwhelming without guidance. Parents should help children design simple experiments (measuring field strength at different distances, comparing different magnets) rather than wandering randomly.
Tinybop Simple Machines — Best Interactive Simulation
While not exclusively about magnets, Tinybop’s Simple Machines app includes an excellent magnetism section where children experiment with magnetic materials, observe attraction and repulsion, and use magnets to solve mechanical puzzles. The playful interface lets children drag objects near magnets to discover which materials are magnetic (iron, nickel, cobalt) and which are not (wood, plastic, copper, aluminum).
Why parents love it: The discovery-based approach lets children test predictions. Before dragging each material toward the magnet, children can guess whether it will be attracted, building scientific thinking habits alongside content knowledge.
Limitation: Magnetism is one section of a broader app. Children seeking deep magnetism content will need additional resources.
MEL Science AR — Best Augmented Reality
MEL Science uses augmented reality to project 3D magnetic field visualizations into the child’s physical space. Children can place a virtual magnet on their desk and walk around it, observing field lines from every angle. Bringing two virtual magnets together shows field interaction in three dimensions, including the distinctive patterns created by attraction and repulsion.
Why parents love it: The AR approach makes abstract physics spatially concrete. Children who struggle with 2D diagrams often grasp magnetic fields immediately when they can walk around a 3D visualization in their own room.
Limitation: The subscription model ($9.90/month) is expensive for a single topic. The free trial provides enough content for initial exploration, but full access requires ongoing payment.
ScienceWiz Magnetism — Best Structured Lessons
ScienceWiz Magnetism provides step-by-step lessons that progress from basic attraction and repulsion through compass construction, electromagnet building, and motor principles. Each lesson combines a brief explanation, an interactive simulation, and a suggested real-world experiment using household materials. The structured progression ensures no conceptual gaps.
Why parents love it: The clear lesson structure makes this app ideal for methodical learners who want to build understanding systematically rather than exploring freely. The real-world experiment suggestions bridge digital and physical learning.
Limitation: The structured approach may feel rigid to children who prefer open-ended exploration.
What to Look For
The best magnet apps make invisible fields visible. Look for field line visualizations that update in real time as children move magnets, and simulations that allow children to test whether different materials are magnetic. Apps that connect magnetism to electromagnetism help children understand that magnetism and electricity are aspects of the same force, preparing them for more advanced physics.
Pair app learning with physical magnets. Bar magnets, iron filings, and a compass cost under ten dollars and provide tactile experiences that no simulation can fully replace. The app visualizes what the child feels with real magnets, creating a powerful combination.
