The gradient in field strength gives rise to a magneticpressure force that tends to stretch the wire uniformly outward. If enough current travels through the wire, then the loop of wire will form a circle . At even higher currents, the magneticpressure can create tensile stress that exceeds the tensile strength of the wire itself, causing it to fracture or even explosively fragment. Management of magneticpressure is a significant challenge in the design of ultrastrong electromagnets. Magneticpressure can be used to propel projectiles this is the operating principle of a railgun . If any currents present are parallel to the field, the magnetic field lines follow shapes in which the magneticpressure gradient is exactly balanced by the magnetic tension force .

The average power in a given period is equal to zero. Due to its dependence on frequency, magnetic inductance is mainly observable in magnetic circuits which operate at Very high frequency VHF and or Ultra high frequency UHF frequencies.

A magnet was run across this stripe. The encoding has been made visible by applying a Magnetic Developer solution Magnetic developer is a fluid which makes the magnetism magnetic information written on magnetic tape or the magnetic stripe of a credit card or ATM card visible to the naked eye. Magnetic developer can be found in liquid or aerosol form. When applied to a magnetic stripe, suspended metal particles will be attracted to the magnetically charged regions of the stripe as the liquid evaporates. Magnetic developer can be used to troubleshoot problems with magnetic stripes and the equipment that encodes and reads them. By making the encoding visible, one can see how encoding head alignment affects the position of the data tracks, and observe any possible magnetic damage that has occurred on the magnetic stripe.
