magnetic force acting on it called?
Answer Magnetic Field
3. What is the name of an electric device that converts kinetic energy into electric
energy?
Answer Generator
4. True or False
Answer According to Lenz's Law, the direction of the Emf induced is always
opposite the changing magnetic field.
Answer True

mutual magnetic fields?
Answer Transformer
8. True or False
Answer When drawing magnetic field lines around the North pole of a bar
magnet, they should be drawn away from the North pole.
Answer True
9. When drawing magnetic field lines, if the lines are getting closer together,
