The motor effect

Question 1

What happens when a current carrying conductor is put between magnetic poles?

Answer 1

The magnetic field around the wire interacts with the magnetic field it has been placed in. This causes the magnet and the conductor to exert a force on each other. This is called the motor effect and can cause the conductor to move.

Question 2

What can I think of the motor effect as?

Answer 2

A slingshot

Question 3

What angle does the wire need to be at to experience the full force?

Answer 3

90°

Question 4

What extent of the force does the conductor experience when it’s at an angle of 90°?

Answer 4

The full force

Question 5

What will happen if the conductor runs parallel to the magnetic field? What about angles in between?

Answer 5

It won’t experience any force at all. At angles in between it’ll feel some force

Question 6

Which way does the force always act?

Answer 6

At right angles to the magnetic field of the magnets and to the direction of the current in the wire.

Question 7

What is the equation for figuring out the force acting on a conductor in a magnetic field?

Answer 7

F=BI1

Question 8

When can the equation F=BI1 be used?

Answer 8

When the current is at 90° to the magnetic field it’s in the force acting on it can be found using that equation.

Question 9

What does F stand for in F=BI1?

Answer 9

Force(N)

Question 10

What does B stand for in F=BI1?

Answer 10

Magnetic influx density (T,tesla)

Question 12

What is B the measurement of?

Answer 12

The size of the current through the conductor.

Question 13

What does I stand for in F=BI1?

Answer 13

Current (A)

Question 14

What does 1 stand for in F=BI1?

Answer 14

Length (M)

Question 15

What is 1 the length of?

Answer 15

The conductor that’s in the magnetic field
