The emf induced between the ends of the wire is about 50 μV

<h3>Further explanation</h3>
Let's recall the induced emf formula for straight wire moving in magnetic field as follows:

where:
<em>ε = induced emf ( V )</em>
<em>B = magnetic field strength ( T )</em>
<em>L = length of wire ( m )</em>
<em>v = speed of wire ( m/s )</em>
<em>B, L , v are mutually perpendicular</em>
Let us now tackle the problem!
<u>Given:</u>
speed of wire = v = 2.0 m/s
length of wire = L = 50 cm
magnetic field strength = B = 50 μT → <em>vertical component</em>
<u>Asked:</u>
induced emf = ε = ?
<u>Solution:</u>






<h3>Conclusion:</h3>
The emf induced between the ends of the wire is about 50 μV
