Question

Почему кольцо с разрезом не реагирует на приближение магнита?​

Answer 1

Ответ:

Кольцо с разрезом не реагирует на приближение магнита, потому что в нём не возникает индукционный ток.

Объяснение:

Answer 2

Why doesn't a ring with a gap react to the approach of a magnet?

When a ring has a gap, it can be considered as two separate loops of wire that are not connected. This configuration affects the way the ring interacts with a magnet.

When a magnet is brought close to a ring with a gap, the magnetic field lines from the magnet induce an electric current in the ring. This induced current creates its own magnetic field that opposes the magnetic field of the magnet. According to Lenz's law, the induced current will always flow in a direction to oppose the change that caused it.

In the case of a ring with a gap, the induced current flows in one loop of the ring, but it cannot flow through the gap to the other loop. As a result, the induced current creates a magnetic field that opposes the magnetic field of the approaching magnet, but only in the loop where the current can flow. The other loop, separated by the gap, does not experience the opposing magnetic field.

Therefore, the ring with a gap does not react as strongly to the approach of a magnet compared to a complete ring without a gap. The presence of the gap prevents the induced current from flowing through the entire ring, reducing the overall magnetic interaction.
