There are two fundamental types of magnets, permanent and electromagnet. Both of these may be presented in numerous forms, and there seems no merit in considering any particular eleven.

Neodymium magnets are the strongest type of permanent magnets available, with a much higher magnetic strength compared to other types of magnets like ceramic or alnico magnets.
Neodymium magnets are the strongest type of permanent magnets available, with a magnetic field significantly stronger than other types of magnets like ceramic or alnico magnets.

The best types of magnets to use for a magnetic glass board are neodymium magnets. These magnets are strong and durable, providing a secure hold on the glass surface without scratching or damaging it.
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.
Temporary magnets, such as soft iron and steel, are easy to magnetize but lose magnetism quickly because they have low coercivity. These types of magnets can be easily demagnetized by external factors such as heat or mechanical shock.
Umm I dont No:)
