TS EAMCET · Physics · Magnetic Effects of Current
A horizontal wire carries current below which another wire of linear density carrying a current is kept at distance. If the wire is kept below hangs in air, what is the current in this wire when the direction of current in both the wires is same?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Force acting between the wires will be attractive as current flowing in both wires is in the same direction.Now to keep the wire hanging in air, force acting per unit length of the wire due to magnetic field should balance gravitational force.…
