Explanation:
Effect of changing wire diameter on magnetic field:
- When the wire diameter is changed, the magnetic field produced by the current flowing through the wire also changes.
Expression for magnetic field far away from a long straight wire:
- The magnetic field far away from a long straight wire is given by the formula: B = (μ₀ * I) / (2πr)
Relation between magnetic field and wire diameter:
- The magnetic field is directly proportional to the current I and inversely proportional to the distance r from the wire.
Effect of changing wire diameter on magnetic field strength:
- When the wire diameter is changed from 0.5 mm to 1 mm, the current remains the same.
- Since the current is the same, the magnetic field strength will remain unchanged far away from the wire.
Conclusion:
- Therefore, the strength of the magnetic field far away will be unchanged when the wire diameter is changed from 0.5 mm to 1 mm while carrying the same current of 1 A.
