A device that produces magnetism is an electromagnet, which generates a magnetic field when an electric current flows through a coil of wire. Other devices include permanent magnets, which are made from materials that have a persistent magnetic field. Additionally, magnetic fields can be produced by certain electrical devices like motors and generators, where the interaction of electric currents and magnetic fields is fundamental to their operation.
A dynamo. It is hard to produce pure direct current using the induction of a magnet on a coil. In a rotating coil the north and south poles of a magnet will normally cause the current to flow the opposite way, every half turn. In a dynamo, the spinning electromagnet in the centre of the field coils, has many separate windings. The current is switched to each coil make sure the magnetism only has one polarity, at each fraction of a turn. This switch is called a commutator.
You can use a device that detects magnetism. A compass needle may suffice.
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
The Latin translation for Magnetism is Magnetismus.
Repulsion is an antonym for magnetism.

Such a device is known as a generator.

No, a battery is not magnetic. It produces electricity through chemical reactions, not magnetism.
Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).Magnetism is produced through electric currents.

Electric motor
One can accurately measure magnetism in a material or object using a device called a magnetometer. This device can detect the strength and direction of the magnetic field produced by the material or object. By analyzing the data collected by the magnetometer, one can determine the level of magnetism present in the material or object.
