3.1 Magnetic fields: True or False statements:3.1.1 The magnetic field due to a current element is parallel to the currentelement. (2)3.1.2 The magnetic field due to a current element varies inversely with the squareof the distance from the element. (2)3.1.3 The magnetic field due to a long wire varies inversely with the square of thedistance from the wire. (2)3.1.4 Ampères law is valid only if there is a high degree of symmetry. (2)3.1.5 Static electric and magnetic fields are governed by the static forms ofMaxwells equations in differential and integral form for which /t 0. (2)3.2 The plates of a parallel-plate capacitor have each area of 10 2. The capacitorplates are separated by a distance of 2 cm. The capacitor is filled with a dielectricmaterial with = 40, and the voltage across it is given by V(t) = 30cos2 \times 106 t(V). and connected to a supply voltage of 50sin103t V. Calculate thedisplacement current.
