The Motor Effect And Flemings Left Hand Rule

Question 1

What is the motor effect

Answer 1

When a current carrying wire experiences a force due to two magnetic fields acting on each other

Question 2

How can you reduce the force that charged particles experience when they are moving through a magnetic field

Answer 2

Make them move parallel to the field lines

Question 3

What angle does the wire have to be to the magnetic field to experience a force

Answer 3

90 degrees

Question 4

What is the direction of the force proportional to

Answer 4

Direction of current

Question 5

How can you increase the strength of the force

Answer 5

Increase the current
Increase the strength of the magnetic field around
Reversing the direction will reverse the direction of the force

Question 6

What are the three fingers of Flemings left hand rule

Answer 6

Thumb = direction of force
First finger = direction of field
Second finger = direction of current
