Question

We can use an electromagnet to lift very heavy iron loads

• A. True
• B. False

Answer 1

The correct option is A True

The electromagnet is essentially magnetic and can lift heavy loads as needed.

1. However, in the case of a permanent magnet, unloading is impossible because the permanent magnet does not lose its magnetism.
2. This piece of iron attracts magnets between these pieces. Accordingly, the magnet can be divided into predetermined parts.
3. Then the remaining pieces are just iron pieces. So we can separate iron and magnet between given pieces.
