The Magnetic Force on a Current-Carrying Loop
To determine the magnetic force acting on a current-carrying loop placed in a magnetic field, we need to consider the interaction between the magnetic field and the current flowing through the loop.
1. Magnetic Field and Current Direction
The magnetic field is perpendicular to the plane of the circular loop. This means that the magnetic field lines are oriented in a direction perpendicular to the surface of the loop.
The current direction in the loop is crucial in determining the force it experiences. To determine the direction of the force, we can use the right-hand rule. If the current is flowing clockwise in the loop when viewed from above, the force on the loop will be in the upward direction. If the current is flowing counterclockwise, the force will be in the downward direction.
2. Determining the Magnetic Force
The magnetic force on a current-carrying conductor can be calculated using the formula:
F = BILsinθ
Where:
- F is the magnetic force acting on the loop
- B is the magnetic field strength
- I is the current flowing through the loop
- L is the length of the conductor within the magnetic field
- θ is the angle between the current direction and the magnetic field direction
3. Applying the Formula to the Circular Loop
In the case of a circular loop, the length of the conductor within the magnetic field is equal to the circumference of the loop, which is 2πR (R is the radius of the loop).
Since the current in the loop is perpendicular to the magnetic field direction (θ = 90°), the sinθ term becomes 1.
Therefore, the formula for the magnetic force simplifies to:
F = BIL
4. Determining the Answer
Comparing the formula for the magnetic force with the given options, we can see that the correct answer is D) πIRB.
This is because the magnetic force is directly proportional to the current (I), the magnetic field strength (B), and the radius of the loop (R).
