A circular coil with 250 windings (turns) and a radius of 0,04 m, is rotated clockwise inside a magnetic field with a field strength of 3,2 T.
9.1 Calculate the magnetic flux through the coil at the position indicated on the diagram, where the coil is perpendicular to the field. (3)
9.2 If the coil rotates clockwise through 25°, and the potential difference induced is 2,8 V, calculate the time in which this rotation took place. (4)
9.3 Which law can be used to explain the phenomenon described in QUESTION 9.2?
Name and state the law. (2)
9.4.1 If the circular coil is replaced with a square coil with a side length of 0,04 m, and the same movement is made in the same amount of time, will the induced emf be the same as, larger than or smaller than the circular coil?
Write down only THE SAME AS, LARGER THAN or SMALLER THAN. (1)
9.4.2 Explain the answer to QUESTION 9.4.1. (2)
