Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.

Question

Q3. As the magnet moves closer, the flux enclosed within the coil increases. Why?
The coil wants to oppose this change. Thus, it responds with an induced current Ilinduced to
create an opposing induced magnetic field Binduced:
front of coil
Binduced
induced
Note: In this situation, if Binduced, was in the opposite direction, it would add to the
original field and increase the energy of the system!
Q4. If the same magnet moved away from the coil, insert arrows to indicate the directions
of Binduced and Iinduced below. Explain the reasons for your choices in the space below.
Think in terms of Lenz's Law.

Inductive charging is used to wirelessly charge electronic devices ranging front toothbrushes to cell phones. Suppose the base unit of an inductive charger produces a 1.00 103-T magnetic Held. Varying this magnetic Held magnitude changes the flux through a 15.0-turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is 3.00 104 m2 and the induced emf has an average magnitude of 5.00 V. Calculate the time required for the magnetic field to decrease to zero from its maximum value.

Justify the claim that the forces on the sides of the loop are equal and opposite, independent at how much of the loop is in the field and do not affect the net force on the loop.
