How bar magnet is produced

WebAnd for magnetic fields we will require a magnet. So let's bring in a magnet, place it close to this coil and see what happens. And we see nothing. There is no glow in the bulb. That means there is no current, but there is a magnetic field because I have kept a bar magnet close to it. This means a magnetic field does not create an electric current. WebAs a concrete example, consider Figure 20.16, which shows a charge q moving with velocity →v through a magnetic field →B between the poles of a permanent magnet. The magnitude F of the force experienced by this charge is. F = qvBsinθ, 20.4. where θ is the angle between the velocity of the charge and the magnetic field.

WebThe magnetic field produced by the current in a coil of wire: is very similar to the field of a bar magnet; reverses when the direction of the current in the coil is reversed. WebMagnetism. Electromagnetism is the force produced when an electrical current flows through a simple conductor such as a piece of wire or cable. While magnets can be made from ferromagnetic materials which attract (and repel) other materials, mainly metals. Magnetism is the force exerted by magnets as they attract or repel each other.
