What are the non contact forces of electromagnets
The non-contact forces of electromagnets include:
1. Magnetic force: Electromagnets can attract or repel objects without direct physical contact through the magnetic field they produce.
2. Electromagnetic induction: Electromagnetic induction is the process by which a changing magnetic field induces an electric current in a nearby conductor, without direct contact.
3. Lorentz force: The Lorentz force is the force experienced by a charged particle moving through a magnetic field, causing it to change direction without physical contact.
4. Magnetic levitation: Electromagnets can generate a repelling force that can levitate objects above them without direct physical contact.
