Magnetism is a force of attraction or repulsion that acts at a distance.
What are magnets?
Magnets are objects that produce magnetic fields and attract certain metals like iron, nickel, and cobalt.
How do magnets work?
Magnets work by aligning the magnetic domains of their atoms, creating a magnetic field around them.
What is a magnetic field?
A magnetic field is a region around a magnet or a moving electric charge where magnetic forces can be felt.
What are the two ends of a magnet called?
The two ends of a magnet are called the North pole and the South pole.
What happens when two magnets are brought together?
When two magnets are brought together, opposite poles attract each other while similar poles repel each other.
What is magnetic force?
Magnetic force is the force of attraction or repulsion exerted by magnets on each other.
What is electromagnetism?
Electromagnetism is the combination of electricity and magnetism, where electric currents create magnetic fields.
What are some everyday uses of magnets?
Some everyday uses of magnets include compasses, fridge magnets, MRI machines, and speakers.
What is magnetic induction?
Magnetic induction is the process by which a magnetic material becomes magnetized when placed in a magnetic field.
What is the Earth's magnetic field?
The Earth's magnetic field is a magnetic field that extends from Earth's interior out into space, protecting our planet from the solar wind.
What is a magnetic material?
A magnetic material is a material that can be magnetized or attracted to a magnet, such as iron, nickel, and cobalt.
What is a temporary magnet?
A temporary magnet is a magnet that only retains its magnetism for a short period of time.
What is a permanent magnet?
A permanent magnet is a magnet that retains its magnetism indefinitely unless subjected to external factors like heat or a strong magnetic field in the opposite direction.
What is the right-hand rule in magnetism?
The right-hand rule is a way to determine the direction of the magnetic field around a current-carrying wire or the direction of the force on a moving charge in a magnetic field.
What is magnetic levitation?
Magnetic levitation is the suspension of an object using magnetic fields to counteract the force of gravity.
