Magnetic field due to Current Carrying Wire

A Dansh phySest and chemist Hans Christian Orsted . once performing an experiment Saw that a current Poyang in a circuit caused deflection of compass needle which was kept nose to rt.He then concluded that current carping wuo produces Magnetic field

Magnetic held lines due to current carrying wire can also be plotted using iron filings in the same manner as in case of Bar Magnet. Magnitude of magnets head is directly 1100001100a110 current and inversely Proportchat to the &stance from the no

Right hand Thumb RuleTo find the directors of Magnetic field. Right Thumb Rule is used.

Right hand thumb rule stales that if we hold the current carping wire in the right hand and d the thumb points towards the current. the direction in which the fingers encircle gives the direction of Magnetic field.

Magnetic Field due to current in solenoid

Solenoid is a long cod contaosm a large number of dose tums of insulated copper wire. The Magnetic held lees Of a Bar Magnet are smittar to that Of soten04

The magnetic field inside the solenoid is more but less outside rt. Magnetic field Inside solenoid is undorm i e. same everynhere.
