Magnet - Wikipedia

A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent ...

The force produced by a magnetic field

V = g × A. Equation FRV. where g is the gap length and A is the cross sectional area of the coil's core. The total energy is then. W = ( B 2 / (2 μ 0 )) × (g × A) Equation FRT. We need the force on the armature. That is given by the rate of change of energy with gap length. F = dW/dg.

Steel ball bearing in a magnetic field | Physics Forums

A steel ball bearing is placed to the left of the magnet where it is equidistant from the north and south ends. Consequently, a force pushes the ball to the centre of the magnet. From my knowledge of Fleming's left hand rule and induction, a current needs to be present for forces to occur, however I do not see where the currents are.

SMOT Magnetic Accelerator (with Pictures) - Instructables

I understand your explanation but wonder if you are familiar with what happens during magnetic attraction between a magnet and an unmagnetized ferromagnetic material (the steel ball). Basically, there would be no attraction if the magnetic domains in the steel ball did not align with the magnetic field of the external magnets.

Coilgun - Wikipedia

For ferromagnetic projectiles, a single-stage coilgun can be formed by a coil of wire, an electromagnet, with a ferromagnetic projectile placed at one of its ends. This type of coilgun is formed like the solenoid used in an electromechanical relay, i.e. a current-carrying coil which will draw a ferromagnetic object through its center. A large current is pulsed through the coil of wire and a ...

Is Steel Magnetic? Other Metal Magnetic Questions Answered ...

Steel is a Ferromagnetic Material. Technically steel is composed mostly of iron, which is a ferromagnetic material. For example: 1018 steel, a very common grade of steel, is composed of 98.81-99.26% iron. Other ferromagnetic materials include nickel cobalt.

316 stainless steel is slightly magnetic -- will this ...

Plain steel is ferromagnetic. As a result of processing, it may become magnetic, so steel hardware is sometimes passed through a "degausser" to remove any magnetism it has acquired during processing. The degaussing renders it non-magnetic but NOT non-ferromagnetic -- the steel will still be attracted to a magnet.
