GEOLOGY

Detailed explanation-1: -Similar magnetic poles repel and unlike magnetic poles attract each other.

Detailed explanation-2: -The force which attracts objects like iron is called magnetic force. The force of attraction or repulsion which are present between two magnetic materials is known as magnetic force iron is a ferromagnetic materials.

Detailed explanation-3: -A push or pull that an object experiences as a result of interacting with another item are known as a force. When an object applies a force that pulls another object, it is a force of attraction. When an object applies a force that pushes another object away, it is a force of repulsion.

Detailed explanation-4: -That means if we bring two magnets of similar poles (north-north, south-south), then the two magnets repel each other. Use : This technology is used in MagLev Trains. MagLev is a lavitating train that works on magnets repulsion principle. The train track and train wheels are similarly magnetized.
