Unformatted text preview: An induced current always opposes the original change in magnetic flux. Different Examples Whats it good for, Mr. Faradey? Electric Generators Transformers 1. If a charged particle travels in a straight line, can you say that there is no magnetic field in that region of space? Explain. 2. A proton and and electron have the same velocity. What happens if they enter a bending magnet with a magnetic field perpendicular to their velocity?...
