PIIYS 205 Aeignent 2 (Revieion 1) 4. A long conducting wire carries a curre! of 1 = 2.00A and bends making a circular arc of radius r = 10.0cm, as shown. Determine the magnitude ald direction of the magnetic field at point P at the centre of the arc 1 5. A curren I lows parallel to the axis of a long conducting pipe, of inner radius a and outer radius 2a, as shown. If the current is distributed uniformly through the conducting material, find expressions for the magnetic field everywhere © 2015 Athabasca Univer&itv;

Explanation / Answer

4) magnetic field at P is B_p = mu_o*i/(2*r)

Given that current i =2 A

radius is r = 10 cm = 0.1 m

then B= (4*3.142*10^-7*2)/(2*0.1) = 1.25*10^-5 T
