OBJECTIVESOBJECTIVES
• To determine the shape of equipotential surfaces and electric field lines associated to a dipole with:
a) two point charges
b) two parallel plates, and to compare each of
these to theoretical predictions

Are electric and magnetic fields different?
Electric fields are produced wherever there is a voltage
Electric fields can be shielded easily
Magnetic fields are produced by current - the quantity of electricity flowing.
While magnetic fields cannot
Electric Field Vs
Magnetic Field
Electric fields are measured in volts per meter (V/m)
magnetic fields in tesla (T), or amperes per meter (A/m).
