Question 4 :
In which  form  the field lines inside the infinite solenoid are present ?<br/>
Question 5 :
<strong>If $2\%$ of the main current is to be passed through a galvanometer of resistance $G$, then resistance of the shunt required is </strong><br/>
Question 7 :
The pattern of the magnetic field around a conductor due to an electric current flowing through it depends on
Question 8 :
Two long parallel wires are at a distance of 1m. If both of them carry one ampere of current in same direction, then the force of attraction on unit length of the wires will be<br>
Question 9 :
Assertion: Magnetic field due to current carrying solenoid is independent of its length and cross-sectional area.
Reason: The magnetic field inside the solenoid is uniform.
Question 10 :
A closed curve encircles several conductors.The line integral $\int{\vec{B}\cdot d\vec{l}}$ around this curve is $3.83\times {10}^{-7} T-m$. What is the net current in the conductors?
Question 11 :
A magnetic dipole is placed under the effect of two magnetic fields inclined at $\displaystyle { 75 }^{ \circ  }$ to each other. One of the fields has a magnetic induction of $\displaystyle 1.5\times { 10 }^{ -2 }T$. The magnet comes to rest at an angle of $30^o$ with the direction of this field. The magnitude of the other field is:
Question 12 :
A given length of wire can be bent to form a circle or a square of single turn and a current may be established in it. The ratio of magnetic field at the centre of circle to that at the centre of square is :
