Q

if you put a current carrying wire into a magnetic field what happens

A

Q

what is the motor effect

A

When a current carrying wire is put in a magnetic field, the wire experiences a force. This can cause the wire to move.

Q

the induced potential difference and current are larger : (3)

A
  • if we use a stronger magnetic field
  • if we move the wire more rapidly
  • if we shape the wire into a coil
    ( more number of turns then the greater the induced potential difference and current)
