A circular loop of diameter 10 cm, carrying a current of 0.20 A, is placed inside a magnetic field B⃗ =0.30 Tk^. The normal to the loop is parallel to a unit vector n^=−0.60i^−0.80j^. Calculate the magnitude of the torque on the loop due to the magnetic field.

Answers

Answer 1
Answer:

Answer:

The magnitude of the torque on the loop due to the magnetic field is .

Explanation:

Given that,

Diameter = 10 cm

Current = 0.20 A

Magnetic field = 0.30 T

Unit vector

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 .

Answer 2
Answer:

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

where;

  • N is the turn in the coil = -0.6i - 0.8j = √[(-0.6²) +(-0.8²)] = 1
  • I is the current in the coil
  • B is magnetic field
  • A is area

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.

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.
