A long wire carrying I=1.1A of constant current oriented North-to-South (and the current is running northwards) is placed horizo
Tema [17]

Answer:

The absolute value of the angular deviation is 39.3°.

Explanation:

Given that,

Current = 1.1 A

Distance = 0.9 cm

Magnetic field = 20μT

We need to calculate the magnetic field due to wire

Using formula of magnetic field

B=\dfrac{\mu_{0}I}{2\pi d}

Put the value into the formula

B=\dfrac{4\pi\times10^{-7}\times1.1}{2\pi\times0.9\times10^{-2}}

B=24.4\times10^{-6}\ T

B=24.4\ \mu T

We need to calculate the absolute value of the angular deviation

Using formula of direction

\theta=\tan^{-1}(\dfrac{B_{E}}{B_{w}})

\theta=\tan^{-1}(\dfrac{20 \mu}{24.4 \mu})

\theta=39.3^{\circ}

Hence, The absolute value of the angular deviation is 39.3°.

How can we calculate the e.m.f of the battery?.
cluponka [151]

Explanation:

The emf is equal to the work done on the charge per unit charge (ϵ=dWdq) when there is no current flowing. Since the unit for work is the joule and the unit for charge is the coulomb, the unit for emf is the volt (1V=1J/C).
