Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of the magnetic needle placed … more
Electromagnetic induction Moving a magnet around a coil changes the magnetic field inside the coil, which causes current to flow through the coil. This phenomenon is called ‘electromagnetic induction’; the current flowing through the coil is ‘induced current.’ The result … more
Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When the different poles of the magnet are close, they pull each other, and when … more
How can you classify iron and aluminum? Iron cans stick well to the magnet. However, aluminum cans do not stick well to magnets. If the conveyor belt’s last wheel is a magnet, the iron cans are stuck to the magnets … more
