force on a current carrying conductor Flashcards
1
Q
if you put a current carrying wire into a magnetic field what happens
A
the two fields interact and a force is exerted on the wire
( which can cause the wire to move)
2
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.
3
Q
to experience the full force of the motor effect, the wire needs to be at ___* to the magnetic field
A
90 degrees
4
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)
