When a bar magnet is brought close to a coil of wire, it induces a current in the coil as the magnet moves because of the magnetic flux that opposes the applied motion and when it moves out - the pole becomes opposite and the current reverses I understand this but what Happens when the magnet is passing through the inside of the coil at a velocity what does the emf look like?/?Also What would the graph look like if I graphed the EMF throughout this motion of moving the magnet in the coil and out the other side??
A cv joint will not expand or decrease in size like a shock absorber. Instead it pivots and rotates.A cv joint is a bearing that allows your wheels to rotate and turn corners which is the main drive unit on your vehicle
They should maintain a constant length, or driving would become very interesting in a hurry.
have you ever seen a swivel head socket: same idea.
the more the coil moves, and the closer it is, the more EMF there is
