The Motor Effect

Question 1

What is the magnetic flux density?

Answer 1

How many field lines there are in a region

Question 2

What is the motor effect?

Answer 2

When a current-carrying wire is put between magnetic poles, the magnetic field around the wire interacts with the magnetic field. this causes the magnet to exert force

Question 3

How do you experience the full force from the wire?

Answer 3

The wire has to be at 90º

Question 4

What angle does the force act to the magnetic fields?

Answer 4

right angles

Question 5

How can you work out the size of the force?

Answer 5

Force = Magnetic Flux Density x Current x Length

F=BI1
