How might the ability of magnets to attract certain metals relate to the crane?

Physics

stepan [7]2 years ago
7 0

Answer:

When the elctromagnet is ON, it picks up the iron pieces from the other scrap (copper, brass, bronze, aluminium, rubber, plastic, glass etc. that is non-magnetic. Then the crane moves to the designated spot where the iron is to be dumped. Then the electromagnet is OFF and the pieces drop - that is the beauty of soft magnetic materials like iron and electromagnetism. When the current is switched off the magnetism disappears and gravity takes over….

If we used a permanent magnet, the iron pieces would be picked up, but they would be stuck to the powerful magnet and removing them would be a tough task.

A wire 25 m long carries a current of 12 A from west to east. If the magnetic force on the wire due to Earth’s magnetic field is
ra1l [238]
<h2>Answer:</h2>

<em>1.33 x 10⁻ ⁴ T outwards.</em>

<em></em>

<h2>Explanation:</h2>

The equation for the magnetic force (F) on a wire whose length is L and carrying a current I in a magnetic field (B) that is uniform is given by;

F = ILB sin θ          ---------------------(i)

Where;

θ = angle between the direction of the current and that of the magnetic field.

From the question,

F = 4.0 × 10⁻² N

I = 12A

L = 25m

θ = 90°

<em>Substitute these values into equation(i) and solve as follows;</em>

4.0 × 10⁻² = 12 x 25 x B x sin 90°

4.0 × 10⁻² = 300 x B x 1

4.0 × 10⁻² = 300B

0.04 = 300B

B = \frac{0.04}{300}

B = 0.000133

B = 1.33 x 10⁻ ⁴ T

To get the direction of the magnetic field, the right-hand rule is used.

If the right hand fingers are positioned in the correct order specified by the right hand rule, then it would be seen that the magnetic field is directed outwards.

Therefore, the magnitude and direction of the magnetic field at this location is <em>1.33 x 10⁻ ⁴ T outwards.</em>

Which of the following courses might a mechanical engineer take in college?
timofeeve [1]

The course to be likely taken by a mechanical engineer in college is agriculture operations (option A).

<h3>What is engineering?</h3>

Engineering is application of mathematics and the physical sciences to the needs of humanity and the development of technology.

Mechanical engineering is a subfield of engineering concerned with designing and building machines and mechanical systems.

A mechanical engineer is an individual who specialises in the field of mechanical engineering. This means that a mechanical engineer is expected to be vast in the knowledge of designing and building machines for operations in other fields.

One of those fields that a mechanical engineer can build or design machine for is agriculture. Therefore, agriculture operations is the most likely course to be taken by a mechanical engineer in college.
