MAgnetism e.c.

An electron is moving north in a region where the magnetic field is south. The magnetic force exerted on the electron is: 

• zero 
• up
• north
• south 

A magnetic field exerts a force on a charged particle:

• always 
• never 
• if the particle is moving across the field lines
• if the particle is moving along the field lines

Parallel conductors carrying currents in the same direction ..............

• attract each other.

• repel.

• do not effect each other

• rotate each other

• Attract
• Repel
• Do nothing
• Shatter
