To produce a maximum emf of 1.0 V, the angular speed should rotate at 35.368 rad/s.
<h3>What is a uniform magnetic field?</h3>
A uniform magnetic field is depicted by parallel straight lines that are distributed uniformly. The flux path is the same as the path of a tiny magnet's north-seeking pole. The flux channels are continuous, producing closed loops.
For a single loop of wire with a radius of 7.5 cm that rotates about a diameter in a uniform magnetic field of 1.6T. We need to determine the angular speed of rotation for it to produce a maximum electromotive force (emf) of 1.0 V.
Given that:
The radius = 7.5 cm, to convert it to meters, we will divide it by 100.
= (7.5/100) m
= 0.075 m
The area A of the wire is computed by using the formula:
A = πr²
A = π(0.075)²
A = 0.01767 m²
Imagine a coil with N turns with area A rotating at a constant angular velocity (q) inside a flux density of a (B) of a magnetic field, with its axis parallel to the field.
The maximum e.m.f can be computed by using the formula:
Where;
- Magnetic field (B) = 1.6 T
Making the angular speed (ω) the subject of the formula, we have:
ω = 35.368 rad/s

What is the vertical component of its velocity at launch? v0y = 20*sin(53) = 16 m/s
Its horizontal component of velocity? v0x = 20*cos(53) = 12 m/s Neglect icing air friction, which of these components remains constant throughout the flight path? The horizontal component. (the vertical component is affected by gravity)
Which of these components determines the projectile's time in the air? The vertical component. (because the projectile falls down after t = 2*v0*sin(53)/g, you can see it doesn't depend on the horizontal component)
