If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. A bar magnet will attract all ferromagnetic materials such as iron, nickel, and cobalt. Therefore, the key difference between bar magnet and electromagnet is that bar magnet has a permanent magnetic field whereas electromagnets have a temporary magnetic … They all have the same strength. located in Northern Canada. This shows the field lines around a disk magnet where the North pole is at These characteristics make the EMG-SA more versatile than most single-coil pickups. Arrives before Christmas. Bring your magnet next to the compass. This shows the field lines around a long bar magnet. A magnet’s power is focused at the poles and lessens at the sides.

This is called the north-seeking pole of the magnet, or simply the north pole. other things and enter the South pole of the magnet. If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value. Every bar magnet has 2 poles. How P-90s differ from other pickups will be discussed later in this article.
