Question about electromagnet induction in a coill.

In summary, rotating a bar magnet in a coil will not produce an alternating current if the magnet is represented as a perfect magnetic dipole. However, if the magnet is facing the other way, it may produce an alternating current when moved through a coil in different directions. The number of turns in the coil may also affect the production of an alternating current.

If you have a bar magnet in a coil and rotate it sideways (poles on the side of the magnet) does it produce an alternating current and do the number of turns in the coil affect this, and if you move a magnet through a coil one way and then the other, does it produce an ac current?

If you are representing your bar magnet as a perfect magnetic dipole (which is a valid representation in some cases), then your answer is no, since the field of a perfect magnetic dipole has cylindrical symmetry and will be unchanged when rotated about it's axis.

What if the magnet was facing the other way?
 

1. How does electromagnet induction work in a coil?

Electromagnet induction in a coil occurs when a changing magnetic field passes through the coil, creating an electric current. This is also known as Faraday's Law.

2. What is the difference between electromagnet induction and regular induction?

Electromagnet induction specifically refers to the creation of an electric current in a coil due to a changing magnetic field. Regular induction can refer to the creation of an electric current in any conductor due to a changing magnetic field.

3. Can electromagnet induction in a coil be used to generate electricity?

Yes, electromagnet induction in a coil is commonly used in generators to convert mechanical energy into electrical energy.

4. How is the strength of the induced current in a coil determined?

The strength of the induced current in a coil is determined by the rate of change of the magnetic field passing through the coil, the number of turns in the coil, and the resistance of the coil.

5. Are there any real-life applications of electromagnet induction in a coil?

Yes, electromagnet induction in a coil is used in a variety of real-life applications such as generators, transformers, and induction cooktops.
