Net magnetic field formula
WebThis article deals with magnetic field strength formula. Magnetic Field Strength refers to one of two ways that the expression of a magnetic field can take place. It is certainly different from the magnetic flux density. … Webdiscussion of a basic torque formula. The formula for the net torque on any current distribution, which is exact in a constant magnetic field, is given in terms of the “magnetic dipole moment” or simply “magnetic moment” µ→ with: with µ→ itself to be discussed shortly. This cross-product can be taken with respect to any
