Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): A small coil carrying current, in equilibrium, is perpendicular to the direction of the uniform magnetic field.
Reason (R): Torque is maximum when the plane of the coil and the direction of the magnetic field are parallel to each other.
Explanation:
To understand this assertion and reason, let's first discuss some basic concepts related to magnetic fields and forces on current-carrying conductors.
When a current-carrying conductor is placed in a magnetic field, it experiences a force due to the interaction between the magnetic field and the current. This force is known as the magnetic force. The direction of this force can be determined using Fleming's left-hand rule.
The magnetic force on a current-carrying conductor can be given by the equation:
F = BILsinθ
Where:
F is the magnetic force,
B is the magnetic field strength,
I is the current flowing through the conductor,
L is the length of the conductor, and
θ is the angle between the direction of the current and the magnetic field.
From this equation, we can see that the magnitude of the magnetic force is maximum when the angle between the current and the magnetic field is 90 degrees (perpendicular). This means that the conductor experiences the maximum force when it is perpendicular to the magnetic field.
Now, let's consider a small coil carrying current. When the coil is placed in a magnetic field, each side of the coil experiences a force due to the interaction between the magnetic field and the current in that side. These forces create a torque on the coil.
The torque acting on the coil can be given by the equation:
τ = NABsinθ
Where:
τ is the torque,
N is the number of turns in the coil,
A is the area of each turn of the coil,
B is the magnetic field strength, and
θ is the angle between the plane of the coil and the direction of the magnetic field.
From this equation, we can see that the torque is maximum when the angle between the plane of the coil and the magnetic field is 90 degrees (perpendicular). This means that the coil experiences the maximum torque when it is perpendicular to the magnetic field.
Therefore, the assertion (A) is true as a small coil carrying current, in equilibrium, is indeed perpendicular to the direction of the uniform magnetic field. However, the reason (R) is not the correct explanation of assertion (A) as the torque being maximum when the plane of the coil and the direction of the magnetic field are parallel to each other is incorrect.
Reason (R): Torque is maximum when the plane of the coil and the direction of the magnetic field are parallel to each other.
