One reason why we know that magnetic fields are not the same as electric fields is because the force exerted on a charge +q
Select one:
a.
is in opposite directions in electric and magnetic fields.
b.
is parallel to a magnetic field and perpendicular to an electric field.
c.
is zero in both if the charge is not moving.
d.
is parallel to an electric field and perpendicular to a magnetic field.
e.
is in the same direction in electric and magnetic fields.
