what is the magnetic flux density in the air gap? described in 3d)i) what is the new 2 e) i) If a coil is made of 400 turns over a length of 20 cm and is wound around a core with relative permittivity of 3500 and a cross-sectional area of 1x10 m². What is the inductance of the coil? ii) If the coil described in 3e)i) is connected up with a resistor of 2002, a switch and a 12 V battery. How long does it take the current to reach 63% 1, when the switch is closed? Total 25
