CIRCLE YOUR FINAL ANSWER (11) each questions (a-f) worth 2 points euch: (a) what is SI unit of magnetic field (b) f Bd -0 is a consequence of magnetie monopoles don't exists: TRUE FALSE (c) Magnetic field lines can cross each other : YES NO (d) Magnetic field produced inside a toroid is: Uniform magnetic field and does not depends on radius: TRUE FALSE (e) If you want to measure current in a circuit using ammeter : how should you connect the ammeter in circuit: in SERIES PARALLEL (o Ir a 100 w resistor is connected with 120 V potential difference Can you estimate the currens flowing through it ?: (g) A cylindrical conductor of radius R carries a non uniform current I. The current density j a function of the radius according to j = cr, where c is a constant. Find magnetic field inside t conductor at a distance r, where( r

Explanation / Answer

a)The SI unit of magnetic field is Tesla.

b)True

flux = 0 implies no magnetic monopole.

c)No

The never cross/intesect each other

d)true

B = u0 N I/(2 pi r)

where r is the radial distance

e)Series

for most accurate measurement of current ammeter should be connected in series.

f)P = VI

I = P/V = 100/120 = 0.83 A

Hence, I = 0.83 A
