WebInvisible magnetic fields can be revealed with iron filings. Eye protection is important when using iron filings. Plotting compasses can be used to investigate the shape of a magnetic field. WebSince we are only going to observe a force in a purely magnetic field we can immediately set E = 0. In addition, if we are looking at a steady flow of charged particles it will be better for our purposes to look at the chunk of force produced by a small current element Idl due to a magnetic field B. That differential force is: dF =Idl ×B (3)
