A coil carrying a heavy current and having large number of turns is mounted in a N - S vertical plane. A current flows in the clockwise direction. A small magnetic needle at its centre will have its north pole is

A tangent Galvanometer is connected directly to an ideal battery. If the number of turns in the coil is doubled, the deflection will

Two tangent galvanometers $A$ and $B$ have coils of radii $8 \mathrm{cm}$ and $16 \mathrm{cm}$, respectively, and resistance $8 \mathrm{\Omega }$ each. They are connected in parallel with a cell of emf $4 \mathrm{V}$ and negligible internal resistance. The deflections produced in the tangent galvanometers $A$ and $B$ are $30°$ and $60°$, respectively. If $A$ has $2$ turns, then $B$ must have

A compass needle free to turn in a horizontal plane is placed at the centre of a circular coil of $30$ turns and radius $12 \mathrm{cm}$. The coil is in a vertical plane making an angle of $45°$ with the magnetic meridian. When the current in the coil is $0.35 \mathrm{A}$, the needle points west to east.
The current in the coil is reversed and the coil is rotated about its vertical axis by an angle of $90°$ in the anticlockwise sense looking from above. Predict the direction of the needle. Take the magnetic declination at the places to be zero.
