What to Focus On

  • Current produces a magnetic field around it.
  • Magnetic field lines are concentric circles around a straight wire.
  • Direction given by the right-hand grip rule.

  • Quantitative law for magnetic field due to a current element.
  • Field depends on current, length, angle, and distance.
  • Direction given by right-hand rule.

  • Field at center of circular loop: B = μ₀I/(2r)
  • For n turns: B = μ₀nI/(2r)
  • Direction by end rule: clockwise → south pole; anticlockwise → north pole.

Common Mistakes to Avoid

Magnetic field due to a current-carrying wire depends on the material of the wire.

A moving charge always experiences a magnetic force in a magnetic field.

The magnetic field inside a solenoid depends on its radius.

Memory Tips

Oersted's Experiment – Current creates magnetic field

Right-Hand Grip Rule for magnetic field direction

Biot-Savart Law: dB ∝ (I dl sinθ)/r²

Magnetic field at center of circular loop: B = μ₀I/(2r)
