Faraday's Law (h1)
Scene Summary (h2)
Faraday's Law is an interactive sim. It changes as you play with it.
The play area has a light bulb circuit, and a moveable bar magnet. There are controls that change what is connected to the circuit, flip the bar magnet North and South poles, and reset the sim.
Move the magnet to play.
Play Area (h2)
Light Bulb Circuit (h3)
(If single just 4 loop coil attached) The
In circuit are a light bulb circuit has a and 4 loop coil connected. The coil is open on the left and right , allowing - the bar magnet to can pass through.
(If both coils) The light bulb circuit has a 2 loop and 4 loop coil connected. Both 2 loop or volt meter attached)
In circuit are a:
- 4 loop coil
- 2 loop coil (if enabled)
- Volt meter (if enabled)
The coils are open on the left and right , allowing - the bar magnet to pass through.
(If volt meter showing) A volt meter attached is attached to the circuit.
(If field lines visible and single coil) From the magnet's position, a[field strength]
magnetic field is passing through the 4 loop coil.
(If field lines visible with DIFFERENT intensities, and both coils showing) From the magnet's position, a[field strength]
magnetic field is passing through the 4 loop coil, and a [field strength]
magnetic field is passing through the 2 loop coil.
(If field lines visible with SAME intensities, and both coils showing) From the magnet's position, a[field strength]
magnetic field is passing through both the 4 loop coil, and the 2 loop coil.Static)
Controls:
- Checkbox: Connect volt meter to circuit
- Checkbox: Show field
- Checkbox: Add 2 loop coil to circuit
Magnet (h3)
(If just 4 loop coil attached)
The bar magnet is at the [ location ]
of the Play Area.
(If single 2 loop coil attached)
The bar magnet is:

The magneticField Lines (h3)
Magnetic field lines are going go around from North pole end on [right / left / right]
end side of magnet, to South pole end on [left / right / left]
end of magnet.Button: flip magnet side of magnet.
(If just 4 loop coil attached)
From the magnet's position, a[field strength]
magnetic field is passing through the 4 loop coil.
(If 2 loop coil attached)
The magnet field strength is:

at the 4 loop coil.[field strength]
at the 2 loop coil.
