Hey mate!!
Magnetic Field Generated by Current:
(a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire.
(b) Right hand rule 2 states that, if the right hand thumb points in the direction of the current, the fingers curl in the direction of the field.
