Igcse Model Questions Vol1 2021 Physics Question 13
Practice objective / multiple choice question 13 from the 2021 Igcse Model Questions Vol1 Physics examination.
A rectangular coil of 200 turns and area \(0.030\,\text{m}^2\) rotates at constant angular speed \(\omega\) in a uniform magnetic field of magnitude \(0.50\,\text{T}\). The coil is connected to a resistor of \(10\,\Omega\). The average power dissipated in the resistor is measured to be \(3.0\,\text{W}\). Find the angular speed \(\omega\) in rad s⁻¹, giving your answer to two significant figures.
