The Original K&J Magnet Calculator. Pull Force.
Note The magnetic field of solenoid is usually uniform along the axis and weak outside the coil.
Magnets exert forces and torques on each other due to the complex rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons)...
The magnetic field around any magnetic material is the region where forces act on other magnetic materials or magnets by inducing the magnetism in them.
...fields, this online calculator can be used to calculate solenoid electromagnetic force by filling in
Magnet Force Calculator. Please select category. Magnetic Calculator for Disc and Cylinder Magnets.
This example of magnetic force calculation illustrates how a simple change in the magnetic circuit increased the lifting force of a magnetic device by a factor of 15.
Magnetic Force Lifting Force Equation and Calculator.
Electromagnets produce magnetic force by running electric current through a wire that wraps around a piece of metal.
Adams' Magnetic Field Calculator calculates the magnetic field strength in Gauss near a disc or rectangle shaped neodymium, samarium cobalt or ceramic magnet.
