Is the positively charged particle has magnetic field around it self??? thanksss fo your help

Electric field lines are generated on positive charges and terminate on negative ones. The field lines of an isolated charge are directly radially outward. The electric field is tangent to these lines. Magnetic field lines, in the case of a magnet, are generated at the north pole and terminate on a south pole.

i would say the answer is food.

hope this !

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
