    Magnet pull force Question's

    Let's say a magnet is attached to an object that weigh's 15 pound's . Then someone attempt's to take the magnet off the object . The object then go's up with the magnet (still being attached to it ) Does that mean the magnet can lift 15 pound's ? Also when a magnet is rotateing through a coil...

    Use ohm's law to (in a parallel kind of way) to predict the outcome of a generator

    I was thinking if the strenght of the permanet magnet could be parallel to I , the rate at which the the magnet (or wire) rotates parallel to V & of course the wire resistance would go with R . If there is some type of way to determine the outcome of a generator before building it, starting it...
