7.3 The Motor Effect

Question 1

What happens if you put a current carrying wire between magnetic poles

Answer 1

The magnetic field around the wire interacts with the magnetic field it has been placed in. - magnet and conductor to exert force on each other and cause the wire to move

Question 2

To experience full force what has to happen ?

Answer 2

The wire has to be at 90 degrees to the magnetic field

Question 3

What happens if the wire runs parallel to the magnetic field?

Answer 3

It won’t experience any force at all

Question 4

What is a good way to show the direction of the force to the magnetic field ?

Answer 4

Apply current to set of nails inside horseshoe magnet

A bar is placed on the rails which completes the circuit thesis generates a force that rolls the bar along the rails

Question 5

What angle does a force act to the magnetic field ?

Answer 5

90 degrees

Question 6

What increases with the strength of the magnetic field ?

Answer 6

The force

Question 7

What does the force also increase with ?

Answer 7

The amount of current passing through the conductor

Question 8

How can you find the force acting on the conductors in a magnetic field

Answer 8

F=BIL

force = magnetic flux density (t), current (A) and length (m)
