The magnitude of the torque on the loop due to the magnetic field is .
Diameter = 10 cm
Current = 0.20 A
Magnetic field = 0.30 T
We need to calculate the torque on the loop
Using formula of torque
Where, N = number of turns
A = area
I = current
B = magnetic field
Put the value into the formula
Hence, The magnitude of the torque on the loop due to the magnetic field is .
The magnitude of the torque on the loop due to the magnetic field is 1.571 x 10⁻³ Nm.Torque on the loop
The torque on the loop is calculated by using the following formulas;
τ = NIBAsinθ
A = πr²
A = πd²/4
A = π(0.1)²/4 = 7.855 x 10⁻³ m²
τ = 1 x 0.2 x (7.855 x 10⁻³) x sin90
τ = 1.571 x 10⁻³ Nm.

Compared with a car moving at some original speed, how much work must the brakes of a car supply to stop a car that is moving twice as fast.
Compared with a car moving at some original speed, four times work must the brakes of a car supply to stop a car that is moving twice as fast. Stopping distance should also be four times.
What happened from the mid 1700s to the mid 1800s that contributed to the change in the global human population?
Industrial revolution is the reason of human population increase in 1700's and 1800's.Explanation:
Industrial revolution is the event that took in the 18th and early 19th century in Europe and then to other parts of the world. In this revolution, there was huge implementation of machines and artificial objects in the daily lives which hugely contributed to the development of quality of product, greatly decreased the production time and costing, etc.
This led to increase in luxury in the lives of people and there was widespread change in the mode of living of the people all over the world.
Without __________, atoms would carry a positive charge. A. protons B. photons C. neutrons D. electrons
How do I calculate the speed of light and the distance between the earth and the moon?
To calculate the distance to a star, astronomers observe it from different places along Earth's orbit around the Sun. If they measure the object's position several months apart, their "two eyes" will have a separation of well over 100 million miles!
