TS EAMCET · Physics · Magnetic Effects of Current
The force acting on a current carrying wire joining two fixed points and in a uniform magnetic field
- A increases exponentially with increase in current
- B is inversely proportional to the magnitude of the magnetic field
- C is independent of the shape of the wire
- D is parallel to the direction of the magnetic field
Answer & Solution
Correct Answer
(C) is independent of the shape of the wire
Step-by-step Solution
Detailed explanation
The formula of force due to current-carrying wire in terms of strength of magnetic field and length of the wire and current,F=iBlsinθ,it is depends on the direction of the magnetic field. And the strength of the force does not depends on the shape of the wire.
