Force on a Current Carrying Conductor in a Magnetic Field

Question 1

Definition of electromagnetic force

Answer 1

Temporary magnet whereby magnetism depends on the magnetic flow

Question 2

What do electromagnet depends on?

Answer 2

Interaction between permanent magnet and current conductor

Question 3

What is a catapult field?

Answer 3

Catapult field is the resultant force produced by the interaction of magnetic field in permanent magnet and current-carrying conductor.

Question 4

How is the magnetic field of the dot and x

Answer 4

x - current flow clockwise (poison! close the bottle tight)

dot- Anticlockwise ( not poison)

Question 5

Which pole does the direction of magnetic field flow from?

Answer 5

north to south

Question 6

How to have stronger Catapult Force?

Answer 6

When the direction of magnetic field for permanent magnet and current-carrier conductor is the same

Question 7

We can determine the direction of straight conductors magnetic field by using…

Answer 7

right hand grip rule

Question 8

Determine direction of force by?

Name the fingers involve and their function.

Answer 8

Fleming’s Left Hand Rule
Thumb : Direction of Force
Index Finger: D. of Magnetic Field
Middle Finger: D. of current flow

Question 9

Factors affecting the magnitude of force on the current-carrying conductor in a magnetic field

Answer 9

- Magnitude of current 
\: The larger the moc, the larger force produce 
\: Increase magnitude of EMF 
\: Use coil instead of straight wire 
\: use short wires 

• Amount of coils increase
• Strength of magnetic field
  : Stronger magnet
  : place magnets close to each other

Question 10

Dot current is away or towards you?

Answer 10

Towards

Question 11

What current is away from you?

Answer 11
