What are the non-magnetic materials being used in the electromagnets?

Non-magnetic materials, by definition, do not exhibit magnetic properties of attraction or repulsion. However, they can play important roles in the construction and operation of electromagnets. While the core of an electromagnet must be made of a ferromagnetic material to carry and amplify the magnetic field (e.g., iron, nickel, cobalt), non-magnetic materials are also used in various parts of an electromagnet for other purposes:

1. Copper: This is a common material for the winding coils around the electromagnet’s core. Copper is chosen because it is an excellent conductor of electricity, which is necessary for creating the electromagnetic field. It has a low resistivity, which means it doesn’t lose much energy in the form of heat when electric current passes through it.

2. Insulating Materials: Materials that do not conduct electricity, such as plastic, rubber, or lacquer, are used to insulate the copper wire. This prevents the current in the coil from short-circuiting by jumping from one loop of the coil to another.

3. Structural Materials: Non-magnetic metals and alloys, such as aluminum or stainless steel (certain types that are not significantly magnetic), may be used in the structural components of electromagnets. These materials provide strength and durability without interfering with the magnetic field generated.

4. Cooling Systems: In high-power electromagnets, non-magnetic materials are used in the construction of cooling systems to prevent overheating
