The magents has                          charge

• anod and cathode
• postive and negative
• north and south poles
• none

The group of force lines going from the N. pole to the S. pole of a magnetis called as

• magetic stregth
• magnetic flux
• flux density
• field stregth

Unit of magnetic flux is                              

• weber
• ampere
• farad
• volts

the number of magnetic field lines passing through a surface

• magetic stregth
• magnetic flux
• flux density
• field stregth

Unit of magnetic flux density is                              

• Ampere-turn
• Wb/m2
• tesla
• Both B & C

The symbolof magnetic flux density is             

• B
• H
• R
• S

Unit of magnetic field strength is                              

• Ampere-turn
• Wb/m2
• tesla
• ampere-turns per meter.

The symbolof magnetic field strenth is             

• B
• H
• R
• S

Current in a conductor produces a magnetic field. Force that produces the magnetic field is called as

• field stregth
• flux density
• premititvity
• MMF

The unit of MMF is                          

• weber
• henry
• farad
• Ampere-turn
