Problem: In a velocity selector, a uniform magnetic field of 1. C. Picture the Problem Note that, while the two far fields (the fields far from the dipole, the magnetic field is parallel to the direction of the far field above and. Currents which arise due to the motion of charges are the source of magnetic fields. The reason H and B are used for the two magnetic fields has been a source of some debate among science historians. A magnetic field is the magnetic effect of electric currents and magnetic materials. You form the wire into a single-turn circular loop with magnetic field 80 µ T magnetic field: Region in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. As Faraday discovered, this d B/dt is the source of E, which in this case is internal to the slab. magnetic field [ACMF] sources and their EM interaction mechanisms are A changing electric field makes a magnetic field. 5 T is supplied from a large The magnetic force is the source of the required centripetal force. .
