Electromagnet
Coulomb's Law - The law of force
F = the force on each charge
+ indicates repulsion
- indicates attraction
k = the electrostatic constant
q1 = the quantity of charge
measured in coulombs
q2 = the quantity of charge
measured in coulombs
r = the radius of separation from
the center of one charge to the
center of the other charge
Properties of field lines
• Direction of lines is in the direction of the electric field
• The density of the lines represent the intensity of the
electric field
• The number of lines of charge entering or leaving the
charge is proportional to the magnitude of the charge
• Field lines leave the positive charge and enter the
negative charge
• Electric field lines never intersect
• Field lines begin and enter perpendicular to surface
of conductor
The difference between electric
and magnetic field lines
=> Electric field exerts forces on
electric charges
=> Magnetic field exerts forces
on magnetic poles
=> An electric field exerts no force
on a stationary magnetic pole
=> A static magnet can not generate an
electrical induction!
Curling Fields
Charged particles moving in magnetic
field => magnetic force
Magnetic force + electric force
=> Lorenz force
Resulting Lorenz force:
