Igcse Model Questions Vol1 2023 Physics Question 11
Practice objective / multiple choice question 11 from the 2023 Igcse Model Questions Vol1 Physics examination.
A long solenoid \(0.50\ \text{m}\) long has \(800\) turns and carries a current \(I\). A straight horizontal wire \(10\ \text{cm}\) long carrying a current of \(2.0\ \text{A}\) is placed at the centre of the solenoid, perpendicular to the solenoid's magnetic field. The wire has a mass of \(20\ \text{g}\). Determine the current \(I\) (in amperes, to the nearest ampere) required so that the magnetic force on the wire equals its weight.
