If the loop sits in a uniform magnetic field of 3.5~T3.5 T that is oriented in the horizontal +x direction, what is the magnitude of the torque on the wire loop?

The magnitude of the torque on the wire loop is 3.68 Nm.

Explanation:

Given that,

Magnetic field = 3.5 T

Suppose, A circular wire loop with a radius of 62.7 cm lies flat in the horizontal x-y plane and contains a current of 852 mA that runs counter-clockwise in the wire loop when viewed from above.

We need to calculate the area

Using formula of area

Put the value into the formula

We need to calculate the magnitude of the torque on the wire loop

Using formula of magnetic field

Put the value into the formula

Hence, The magnitude of the torque on the wire loop is 3.68 Nm.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
