" State Biot - Savart's law "

(a) State Biot - Savart law and ecpress it in the vector form. (b) Using Biot - Savart law, law obtain the expression for the magnetic field due to a circular coil of radius r, carrying a current I at point on its axis distant x from the centre of the coil.

(a) State Biot - Savart law and express this law in the vactor form. (b) Two identical circular coils, P and Q each of radius R, carrying currents 1A and sqrt(3)A respectively, are placed concentrically and perpendicular to each other lying in the XY and YZ planes. Find the magnitude and direction of the net magnetic field at the centre of the coils.

State Biot-Savart law.

A: Ampere circuital law is not independent of the Biot- Savart's law. R: Ampere's Circuital law can be derived from the Blot Savart law.

State the Biot-Savart law. Use it to obtain an expression for magnetic field at the centre of a current carrying circular loop.

State Biot-Savart law. Using Biot-Savart law find the magnitude and direction of magnetic field at a point on the axis of a circular coil of radius 'r', distant 'x' from the center having number of turns N carrying current 'I'.

State the Biot-Savart's law for the magnetic field due to a current carrying element. Use this law to obtain a formula for magnetic field at the centre of a circular loop of radius R carrying a steady current I, sketch the magnetic field lines for a current loop clearly indicating the direction of the field.
