Ring of Current

A ring of current is an infinitely thin, Current carrying wire, in a circular loop. It forms magnetic fields are parallel to it’s central axis. #TODO

Magnetic Field §

Formula §

$$\vec{B}=\frac{{\mu }_0}{2R}I\hat{u}$$

• $\vec{B}$ = Magnetic Field
• $R$ = Radius of loop
• $I$ = Current flowing through the loop
• $\hat{u}$ = Direction obtained using right hand rule
