1) a magnetic field at p and q are same in magnitude but direction is opposite

2) the magnetic field at p and q are same in magnitude and direction

3) the magnetic field at p is greater in magnitude than q and direction of magnetic field at p and q are same

4) the magnitude of magnetic field at p is greater in magnitude than q and the direction of field is opposite at both the points

Answer 1

Answer:

a constant current carrying conductor isplaced un the plane of paper as shown below p amd q are two points at distance r1 and r2 from the wire

Answer 2

The magnitude of the magnetic field at p is greater in magnitude than q and the direction of the field is opposite at both the points

Explanation:

• Here we can use the Right-Hand Thumb Rule
• Let us say that current is flowing from bottom to top
• Therefore the curl of the field is given by the fingers of your right hand
• As we can see, the field is "coming out of the page" at Q and "going into the page" at P
• Also. we know that the strength of an electric field is dependent on radius/distance
• Therefore option 4 is correct
