Magnetic field generated by ring current
WebFind out how an electromagnet uses an electrical current to generate a magnetic field with this guide for KS3 physics students aged 11-14 from BBC Bitesize. WebWe have to consider the point charges on the ring. So the total charge isn't the area because the "ring" is assumed to be hollow. So the charge is :- (circumference) * (thickness) * (charge density) Watch the next part and Sal will integrate this equation and obtain a general formula for this situation.
