Jun 12, 2014 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.

Mar 26, 2015 1. The steel –becomes temporarily magnetized- in the magnetic field of the permanent magnet. In fact the field density at the surface of the steel bar is actually higher than the field density at a short distance from the magnet, because steel has a very high magnetic permeability.

Sep 07, 2014 Is this hysteresis effect essentially the same thing as the following effect I have in mind: When a steel ball is immersed into a magnetic field, it gets magnetized in the direction of that magnetic field. If the ball is then quickly rotated for a small angle, its magnetization vector also gets rotated because it takes some short time (energy?) for magnetization to realign.

Oct 22, 2007 There’s energy in the magnetic field in either case. With the steel ball, the system has a way to reduce that field energy by having the ball approach the magnet. A lot of the energy goes into kinetic energy of the ball. For the golf ball, all the field energy just stays in the initial form. Mike W. (published on 10/22/2007)

Aug 29, 2021 It is very difficult to comment as some types of steel will be magnetic as well as some of them will not be magnetic. In the alloy making process, magnetic properties of the core elements such as iron are hampered because of the changes in the microstructure. Some microstructures still exhibit magnetic properties while others cease the same. 1.

Jan 05, 2021 Steel is already magnetic on an atomic level, but when the atoms are arranged at random, their magnetic effect is canceled out on a macroscopic level. All of these methods allow the atom-scale magnets to align with another magnetic field, causing them to all exert a magnetic force in the same direction. [9]

Uniform magnetic fields. A 'hand-waving' explanation might help clarify the physics. Take an initially uniform magnetic field in free space and introduce into it an iron sphere. The flux lines will bend in the vicinity of the iron so that they will converge upon it. Inside the iron the lines will be quite concentrated (though parallel to the ...
