Alerts

Movement Alerts

Magnet Focus Alert

  • "Magnet at [location] of the Play Area. (If first time focusing magnet) Use the W A S D keys to move the magnet. Use number keys Number 1, 2, or 3 keys to jump slide the magnet."

Movement Alert

  • "[step direction]"

Movement Alert: direction or step size change

  • "A [ step size ] step  [step direction ]."

Jump Slide start alert: on release of 1, 2, or 3 key press

  • "Jumping Sliding magnet [jump slide speed] to [jump slide direction] side of play area. Press Space to stop jumpslide."

Jump slide stop alert: Space bar is pressed, bumped into a coil or reached edge of play area

  • "Jumping Sliding stopped."

Jumping sliding in progress

  • "Jumping Sliding to [jump slide direction]."
  • (info) 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."
  • (info) 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."
  • (info) 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]."
  • (info) 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

Volt meter: adding / removing

  • "['Connecting' / 'removing'] volt meter to circuit"

Magnetic field: show / hide

  • "Showing magnetic field lines. [field strength] magnetic field passing through 4 loop coil. [field strength] magnetic field passing through 2 loop coil. (only if 2-loop coil is enabled)"
  • "Hiding magnetic field lines.

2 loop coil: show / hide

  • "['Adding' / 'Removing'] 2 loop coil [to / from] circuit."

Rotate magnet

  • "Flipping magnet: North pole is now on ['left' / 'right']. South pole now on ['right' / 'left']."

Rotate magnet: with visible field lines

  • "Flipping magnet and its magnetic field: North pole is now on ['left' / 'right']. South pole now on ['right' / 'left']."
  • Remark: This is the same description as a regular "Rotate Magnet" alert text with the addition of "and its magnetic field".

Faraday's Law (h1)

Scene Summary (h2)

  • Simulation Play Area contains:
    • (If single coil)
      • a light bulb circuit with a 4 loop coil.
      • a magnet located at the [location] of the Play Area, [proximity] to the 4 loop coil.
    • (If both coils)
      • a light bulb circuit with a 2 loop coil and a 4 loop coil.
      • a magnet located at the [location] of the Play Area, [proximity] to the 4 loop coil, and [proximity] to the 2 loop coil.
  • Move the magnet to play.

Play Area (h2)

Circuit (h3)

The lightbulb circuit has the following parts connected together with wires:

  • (If single coil) a 4 loop coil
  • (If both coils) 2 loop and 4 loop coils
  • (If volt meter showing) a volt meter attached

The coils are open on the left and right, allowing the magnet to pass through.

(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 magnet is at the [ location ] of the Play Area.(If first time focusing magnet) Use the W A S D keys to move the magnet. Number 1, 2, or 3 keys to slide the magnet.

(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.
