Electrical 2 chapter 1 and 2

A freely suspended magnet always comes to rest in

• North south direction
• North east direction
• Both a and b
• None

The group of force lines going from north pole to the south pole of a magnet is called

• Magnetic Flux
• Magneto motive force
• Both a and b
• None

The force that produce magnetic field is

• Flux
• Magnetic flux
• mmf
• None

The unit of mmf is

• Weber
• Ampere turns
• Henry
• None

The opposition of magnetic field is

• Reluctance
• Flux
• Electric field
• Resistance

The unit of reluctance is

• Flux
• Weber
• Ampere
• Ampere turns / weber

The magnetic field has

• Positive and negative
• Phase and neutral
• North and south pole
• None

The force rule states the light charges repel unlike charges

• Oppose
• Attract
• Both a and b
• None

The reluctance is denoted by the letter

• V
• . R
• I
• S

The unit of magnetic flux is

• Weber
• Tesla
• Newton
• None
