A potential difference of 35 mV is developed across the ends of a 12.0-cm-long wire as it moves through a 0.27 T uniform magnetic field at a speed of 6.0 m/s. The magnetic field is perpendicular to the axis of the wire. What is the angle between the magnetic field and the wire's velocity?

Respuesta :

Answer:

Angle between magnetic field and wire velocity is [tex]10.372^{\circ}[/tex]

Explanation:

We have given potential difference e = 35 mV = 0.035 volt

Length of the wire l = 12 cm = 0.12 m

Velocity v = 6 m/sec

Magnetic field B = 0.27 T

It is known that potential difference developed

[tex]e=Bvlsin\Theta[/tex]

[tex]0.035=0.27\times 6\times 0.12\times sin\Theta[/tex]

[tex]sin\Theta =0.18[/tex]

[tex]\Theta =10.372^{\circ}[/tex]

So angle between magnetic field and wire velocity is [tex]10.372^{\circ}[/tex]
