(a)
Strength of the field 2 cm from the wire.
(a)
Answer to Problem 5PP
The magnetic field at 1 cm is two times stronger than at 2 cm.
Explanation of Solution
Given:
Magnetic field strength =
Formula used:
Where, B = magnetic field strength
r = distance
Calculation:
As it is clear from the formula that strength of magnetic field is inversely proportional to the distance.
So, magnetic field strength will be half when the distance is 2 cm
Conclusion:
The magnetic field at 1 cm is two times stronger than at 2 cm.
(b)
Strength of the field 3 cm from the wire.
(b)
Answer to Problem 5PP
The magnetic field at 1 cm is three times stronger than that at 3 cm.
Explanation of Solution
Given:
Magnetic field strength =
Formula used:
Where, B = magnetic field strength
r = distance
Calculation:
As it is clear from the formula that strength of magnetic field is inversely proportional to the distance.
So, magnetic field strength will be three times less when the distance is 3 cm
Conclusion:
The magnetic field at 1 cm is three times stronger than that at 3 cm.
