A circular loop of bigger radius will produce higher magnetic field than a loop of smaller radius, if same current is flowing through both the loops, explain.

A circular loop of radius 0.3 cm lies parallel to amuch bigger circular loop of radius 20 cm. The centre of the small loop is on the axis of the bigger loop. The distance between their centres is 15 cm. If a current of 2.0 A flows through the smaller loop, then the flux linked with bigger loop

A circular loop of radius 0.3 cm lies parallel to amuch bigger circular loop of radius 20 cm. The centre of the small loop is on the axis of the bigger loop. Obtain the mutual inductance of the two loops.

If in circular coil A of radius R, current I is flowing and in another coil B of radius 2R a current 2I is flowing , then the ratio of the magnetic fields B_(A) and B_(B) , produced by them will be

A circular loop of radius R carrying a current is placed in a uniform magnetic field with its plane perpendicular to B. The force on the loop is

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 athe centre of circular loop of radius r carrying steady current I . Sketch the magnetic field lines for a current loop clearly indicating the direction of the field.

Where is the magnetic field uniform and non-unifrom due to current through circular loop?

A circular loop is carrying current and is said to be equivalent to magnetic dipole. Then, a point on the axis of the loop lies in its

Two wires of equal lengths are bent in the form of two loops. One of the loops is a square shaped whreas the other loop is circular. These are suspended in a uniform magnetic field and the same current is passed through them. Which loop will experience greater torque? give reasons.

A circular coil 'A' has a radius R and the current flowing through it is I. Another circular coil 'B' has a radius 2R and if 2I is the current flowing through it, then the magnetic fields at the centre of the circular coil are in the ratio of
