I have this question in my assessment what hes saying is a statement but we need to choose "true or false".
True, your welcome...
dose anyone have the answer's to the entire quiz? aka im from conexxus (ik i spelled that wrong no need to correct me) thanks! :)
oh ok
well can you help me pleas an advantage of using an electromagnet shown on the crane the image below instead of a regular magnet to move cars in a junk yard is that an electromagnet can easily be turned on and of
Nathan -- have patience. We are volunteers, real people, and not robots.
Your question is not a question. It is a statement that electromagnets can be turned on and off. That is true. Do you have a question about this?
To determine an advantage of using an electromagnet shown on the crane instead of a regular magnet in a junk yard, we need to understand the difference between the two types of magnets.
A regular magnet, also called a permanent magnet, produces a constant magnetic field without the need for any external power source. Once magnetized, it holds its magnetic properties indefinitely.
On the other hand, an electromagnet is a type of magnet that requires an electric current to generate a magnetic field. When the current flows through its coils, the electromagnet becomes magnetic, and the magnetic field is proportional to the current passing through it.
Now, let's consider the advantage of using an electromagnet in the context of moving cars in a junk yard:
1. On and off control: One significant advantage of an electromagnet over a regular magnet is that the electromagnet can easily be turned on and off. By controlling the electric current flowing through the coils of an electromagnet, we can enable or disable its magnetic field. This capability allows precise control over the attraction or release of magnetic objects.
In the case of the crane in the junk yard, using an electromagnet means that the operator can turn the magnet on when they want to pick up a car and turn it off when they need to release or drop the car. This on-off control simplifies the operation, saves time, and enhances efficiency compared to a regular magnet, which would constantly attract cars without the ability to release them easily.
In summary, the advantage of using an electromagnet in the crane instead of a regular magnet is its controllability. The operator can easily turn the electromagnet on and off using an electric current, providing convenient control over the magnetic field for picking up and releasing cars in the junk yard.
