A straight wire of length 0.5 meters carrying a current of 4 A is placed in a uniform magnetic field of strength 0.3 Tesla. Calculate the magnitude of the magnetic force acting on the wire if: (i) The wire is placed perpendicular to the magnetic field lines. (ii) The wire is placed at an angle of $30^\circ$ to the magnetic field lines. (iii) The wire is placed parallel to the magnetic field lines.

Q: A straight wire of length 0.5 meters carrying a current of 4 A is placed in a uniform magnetic field of strength 0.3 Tesla. Calculate the magnitude of the magnetic force acting on the wire if: (i) The wire is placed perpendicular to the magnetic field lines. (ii) The wire is placed at an angle of $30^\circ$ to the magnetic field lines. (iii) The wire is placed parallel to the magnetic field lines.

Given data: Length of the wire ($l$) = $0.5\text{ m}$ Current flowing through the wire ($I$) = $4\text{ A}$ Magnetic field strength ($B$) = $0.3\text{ T}$

Question

Accepted Answer

Given data: Length of the wire ($l$) = $0.5	ext{ m}$ Current flowing through the wire ($I$) = $4	ext{ A}$ Magnetic field strength ($B$) = $0.3	ext{ T}$
