U did it the way i asked. nice lol. its plasma btw
Answer:
it probs gos fast then it was it would be easy if u asked us if their was any mass or friton
Explanation:
Answer
Given,
Length of the wire,L = 31 cm = 0.31 m
mass of the wire, m = 9 g = 0.009 Kg
Current in the wire,I = 7 A
Magnetic field strength, B= ?
Equating magnetic force to the weight of the wire.



B = 0.0407 T
For Force to be upward magnetic field direction should be outward of the plane of paper.
