5 Amazing Magnet Experiments To Blow Your Mind!

SOLVED: If a bar of copper is brought near a magnet, what will happen to the copper bar?A. made into an induced magnet. B. unaffected by the magnet. C. attracted by the magnet. D. repelled by the magnet.

SOLVED:A bar magnet induces a current in an N-turn coil as the magnet moves closer to it (Figure P(8.24) . The coil's radius is R cm, and the average induced emf across the bulb during the time interval is ε. (a) Make a list of the physical quantities that you can determine using this information; (b) Is the direction of the induced current from lead a to b, or from b to a? Explain.

A bar magnet is placed in a uniform magnetic field (Fig. P20.7)... | Filo
