Q
Q: In a uniform magnetic field, the magnetic force on a current-carrying conductor is maximum when the angle between the conductor and the field is: (2019)
Solution: The magnetic force is maximum when the angle between the conductor and the magnetic field is 90 degrees, as sin(90°) = 1.
Steps: 6
Step 1: Understand that a current-carrying conductor is a wire through which electric current flows.
Step 2: Know that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Recognize that the magnetic force on the conductor depends on the angle between the conductor and the magnetic field.
Step 4: Remember that the formula for magnetic force (F) is F = I * L * B * sin(θ), where I is current, L is length of the conductor, B is magnetic field strength, and θ is the angle.
Step 5: Realize that the value of sin(θ) varies with the angle θ, and it reaches its maximum value of 1 when θ is 90 degrees.
Step 6: Conclude that the magnetic force is maximum when the angle between the conductor and the magnetic field is 90 degrees.
