Movement Alerts
Magnet Focus Alert (First time focusing)
- "Magnet at
[location]of the Play Area. Use the W A S D keys to move the magnet. Number 1, 2, or 3 keys to slide the magnet."
Magnet Focus Alert (after first time focusing)
- "Magnet at
[location]of the Play Area."
Movement Alert
- "
[step direction]"
Movement Alert: direction or step size change
- "A
[ step size ]step[step direction ]."
Slide start alert: on release of 1, 2, or 3 key press
- "Sliding magnet
[slide speed]to[slide direction]side of play area. Press Space to stop slide."
Slide stop alert: Space bar is pressed, bumped into a coil or reached edge of play area
- "Sliding stopped."
Sliding in progress
- "Sliding to
[slide direction]." 
Alert Frequency: This is a lower priority alert. If one of the other alerts / events has occurred it is not be necessary to give this movement alert.
Coil bump alert
- "Bumped into
[number coils]coil."
Location Alerts
Location change alert: magnet transitions from one location region into another
- "At
[location]of play area."
Coil proximity change alert: magnet transitions from one coil proximity region into another
- Single coil: "
[coil proximity]4-loop coil." - Both coils: "
[coil proximity]4-loop coil.[coil proximity]2-loop coil." - Alert Frequency: This alert is omitted if the user's action will trigger an Entrance Direction or Exiting Coil alert.
Coil proximity change event with magnetic field enabled
- Single coil: "
[coil proximity]4-loop coil and[field strength]magnetic field passing through." - Both coils: "
[coil proximity]4-loop coil and[field strength]magnetic field passing through.[coil proximity]2-loop coil and[field strength]magnetic field passing through." - Alert Frequency: This alert is omitted if the user's action will trigger an Entrance Direction or Exiting Coil alert.
Coil Entrance Direction Alert
- "
[number coils]coil entrance to the[left / right]." - "
[number coils]coil entrance no longer to the[left / right]." - Alert Frequency: this alert should occur only once and during the transition into the region.
Exiting Coil Alert
- "Exiting
[number coils]coil."
Sim Controls Alerts

Faraday's Law (h1)
Scene Summary (h2)
Faraday's Law is an interactive sim. It changes as you play with it.
(If single coil) The play area has a light bulb circuit with a 4 loop coil.
(If both coils) The play area has a light bulb circuit with a 2 loop coil and a 4 loop coil.
There is a moveable bar magnet in the Play Area. The circuit has checkboxes that change what is connected to it. There is also a button to flip the bar magnet and reset the sim.
Move the magnet to play.
Play Area (h2)
Light Bulb Circuit (h3)
(If single coil) The light bulb circuit has a 4 loop coil connected. The coil is open on the left and right, allowing the bar magnet to pass through.
(If both coils) The light bulb circuit has a 2 loop and 4 loop coil connected. Both coils are open on the left and right, allowing the bar magnet to pass through.
(If volt meter showing) A volt meter attached is also 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 and both coils) 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.
- Checkbox: Connect volt meter to circuit
- Checkbox: Show field
- Checkbox: Add 2 loop coil to circuit
Magnet (h3)
The bar magnet is at the [ location ] of the Play Area.
(If single coil) The magnet is [proximity] to the 4 loop coil.
(if both coils) The magnet is [ proximity ] to the 4-loop coil, and is [ proximity ] to the 2-loop coil.
(if field lines hidden) The magnet has two magnetic poles: North on the [left / right], South on the [right / left].
(if field lines visible) The magnetic field lines are going from North pole on [left / right] end, to South pole on [right / left] end of magnet.
