Only when the charge is in motion will a magnetic field exert a force on it. This magnetic force increases whenever we increase the magnetic field strength, or the charge on the particle, or the speed with which the particle moves. The equation that describes these features of the magnetic ...

Equation (1.18) shows that when M is aligned with B→, the potential energy is lowest (most negative), but is highest when M→ and B→ are opposite to each other. The difference between the highest and lowest potential energies is 2|M||B|, where |·| designates magnitude. These ...
“null” distance for a given field strength at the very front by setting velocity equal to zero in equation 7 while satisfying divergent B equal to zero. The calculation indicates that this distance is relatively short (< 1 cm) for the field strength encountered in the present study (< ten...

1a, the induced magnetic dipolar pair interaction displays an anisotropic multi-polar field, either repulsive or attractive depending on the relative position of the grains, and the applied magnetic field direction. The dimensionless number that compares the strength of the magnetic interactions with ...
What is a solenoid? Solenoid magnetic field equation How to calculate magnetic field of a solenoid? FAQs The solenoid magnetic field calculator helps you compute the magnetic field inside a long solenoid. Curious to see what a solenoid is and how to calculate the magnetic field of a solenoid?
1. A cosmic ray electron moves at 7.50 × 106m/s perpendicular to the Earth’s magnetic field at an altitude where field strength is 1.00 × 10−5T. What is the radius of the circular path the electron follows? 2. A proton moves at 7.50 × 107perpendicular t...
Let's consider what that theoretical equation predicts. When we measure a D82 disc magnet from 0.035" away with our magnetometer probe, the calculated, theoretical result should be about 2,643 gauss. Compared with a listed Surface Field of 2,952 gauss, that's a whopping 10% less. That's...
resonance imaging (MRI) machines, where it is necessary to analyze not only the field strength but also the spatial variation of the field. Today’s blog post demonstrates how to compute and plot the gradients of the magnetic field in electromagnetic simulations in the COMSOL Multiphysics® ...
