Answer 1

on ① If it is the velocity of a positive charge tq" and it is subjected to a magnetic field B, deteenine the direction of the magnetic force acting the charged particle is in perpendecular to both vechols u and o change The direction of magnetic force if we the tq to-qui-e negeting charge in the Forces stays in the same direction. If the charged particle (+q) has a velocity uso, and is simul browsily subjected to an electuc field Pin the same direction as B² In the same plane as veches a? and B 4 measting the magnetic susceptibility Xm of a meblic sample it had a value = 1.0002, deteemine the magentic classification is ferromagnetic metal, solenoid, the direction of the magnetic field in pointing downwards. B-H corve of a magnetic matecials on the right, the value Br along the veetical axis represents the the magnetic field intensity.
