According to Lorentz's Force law, what happens to a electron entering horizontally from the left (moving towards right) into a magnetic field pointing into the page?
It goes straight towards right staying on the page.
It deflects upwards staying on the page.
It deflects downwards staying on the page.
It deflects moving out of the page.
What is the formula for the electric field due to a point charge?
E = k * q / r^2
E = q / ε0
E = F / q
E = k * q1 * q2 / r^2

On the surface of the wire.
According to Faraday's law, what induces an electromotive force (emf) in a circuit?
Change in magnetic flux
Change in electric field
Constant electric field
Constant magnetic field
What does Lenz's law state about induced currents?
They oppose the change in magnetic flux
They are always in the same direction as the change
They enhance the change in magnetic flux
They have no effect on magnetic flux
