Answer:

Given Information:

  • Length = 15 cm
  • Breadth = 10 cm
  • Magnetic Field = 2 × 10⁻⁵ Wb
  • Current = 100 mA

According to Electromagnetism, the torque experienced in a Magnetic Field is given by the expression:

⇒ Torque = M × B    [ Cross Product ]

where, M and B are Magnetic Moment and Magnetic Field Vectors respectively.

Also, Magnetic Moment is given by the formula:

⇒ M = I.A

where, I is the current flowing and A is the Area Vector of the current carrying conductor.

Therefore the final formula is given as:

⇒ Torque = (I.A) × B

Now we need to calculate the Area from the given information.

Area of rectangular loop = Length × Breadth

⇒ Area = 15 cm × 10 cm = 150 cm² = 0.015 m²

Substituting all the values in the formula we get,

⇒ Torque = 0.015 m² × 0.1 A × 2 × 10⁻⁵ Wb

⇒ Torque = 0.003 × 10⁻⁵

Torque = 3 × 10⁻⁸ N/m
