The National MagLab is funded by the National Science Foundation and the State of Florida.
These demonstrations about laws and tools associated with electricity and magnetism allow you to adjust variables at and to visualize invisible forces — which makes them almost better than the real thing.
Seeing is believing. In these animations, we show you what electricity and magnetism might look like if they weren't invisible.
Learn about electricity and magnetism — and have some fun while you're at it!
How do Maglev trains work? What are comets made of? How do bugs walk on water? This section demonstrates these and other concepts related to magnetism, electricity and other areas of science.
Whether you prefer your science short & sweet or long & detailed, we spell it out for you here in easy-to-understand language.

Take a field trip to these high magnetic field landmarks around the globe.
You can create a stronger, more concentrated magnetic field by taking wire and forming it into a coil called a solenoid.
Magnetic fields are produced by electric currents. A current-carrying wire will generate around it a circular magnetic field in accordance with the right hand rule.
You can create a stronger magnetic field by forming the wire into a coil. The field is more concentrated in the center of the loop than outside the loop. By adding more loops to a coil, you create an increasingly stronger magnetic field. This is known as a solenoid, demonstrated here:
When the copper solenoid is connected to a battery, it becomes an electromagnet. The ferromagnetic iron filings allow us to physically see the otherwise invisible magnetic fields that surround us every time current travels through a coil of wire.
