How does a non-magnetic piece of metal have an attraction to only one of the poles when you put it near a magnet (it tries to flip to the opposite side)?
A simple magnetic field is a region in space where a magnetic force can be detected. It is created by a magnet or a moving electric charge.
A magnetic field is measured using a device called a magnetometer. This device detects the strength and direction of the magnetic field.
A magnet works by creating a magnetic field around itself. This field has a north pole and a south pole, and opposite poles attract each other while like poles repel.
Yes, magnetic fields can be shielded using materials such as iron, nickel, and cobalt. These materials act as a barrier and redirect the magnetic field, reducing its strength.
Magnets have many practical applications, such as in electric motors, generators, MRI machines, and speakers. They are also used in everyday items like refrigerator magnets, credit cards, and compasses.
