OP warned about not having an attempt at a solution
That's something you are supposed to avoid.Nibesh sharma said:Homework Equations
No idea
The Attempt at a Solution
N/A very very confused what to do about this question..
Assume object A is magnetic material having same pole of the electromagnet's surface it's exposed to.cnh1995 said:That's something you are supposed to avoid.

You are asked to lift an object using an electromagnet. Is object A a permanent magnet? Please state the complete problem clearly.
Yes calculate the power required if the object A is a magnetic material and it is facing the electromagnet with like poles exposed towards the magnetDrClaude said:Surely you can find relevant equations. Also, are you sure that the problem statement is correct: you are asked to calculate the power?
Power is Joules/second. There is no mention of time in your problem.Nibesh sharma said:Yes calculate the power
The problem is now clearer. It is no the power to lift, but to maintain the height against gravity.cnh1995 said:Power is Joules/second. There is no mention of time in your problem.
Right! I was about to delete that but I can't..DrClaude said:The problem is now clearer. It is no the power to lift, but to maintain the height against gravity.
Okay take it this way then... How many watts is it going to take for the electromagnet(if you need to know anything about the specs of magnet just ask) to complete the task?cnh1995 said:Power is Joules/second. There is no mention of time in your problem.
As I posted in your other thread, this is not the way things work here. You have to put in some effort.Nibesh sharma said:Now the solution would be?
okay, the time is 1 sec and the electromagnet's specs is what I'm Trynna figure out here... I want to know what the electromagnets power output should be..DrClaude said:As I posted in your other thread, this is not the way things work here. You have to put in some effort.
I think that your problem is way underdefined. We have no idea what material the hovering object is made of, are any characteristic of the electromagnet.
And the material like I already mentioned: it's magnetic, and if facing the electromagnet as such the like poles of material and magnet are facing each other. I don't know how can I be more clearer atm.DrClaude said:As I posted in your other thread, this is not the way things work here. You have to put in some effort.

Maybe you mean unlike poles face each other?Nibesh sharma said:And the material like I already mentioned: it's magnetic, and if facing the electromagnet as such the like poles of material and magnet are facing each other. I don't know how can I be more clearer atm.
I think the idea is the electromagnet is on the bottom and repelling the object while gravity is pulling down on the object, so you want the same poles facing each other.NascentOxygen said:Maybe you mean unlike poles face each other?
Power is measured in watts (W), which is equal to one joule (J) of energy per second. This unit is used to quantify the rate at which work is done or energy is transferred.
The amount of power required depends on several factors, including the amount of work to be done, the time frame in which it needs to be done, and the efficiency of the system or device being used.
Power can be calculated by dividing the amount of work done by the time it takes to do it. The formula for power is P = W/t, where P is power in watts, W is work in joules, and t is time in seconds.
Power and energy are related, but they are not the same. Power is the rate at which energy is used or transferred, while energy is the capacity to do work. Power is measured in watts, while energy is measured in joules.
Power consumption can have a significant impact on the environment, as it often involves the burning of fossil fuels, which releases greenhouse gases and contributes to climate change. It is important to use power efficiently and consider alternative, renewable sources of energy to minimize the negative effects on the environment.
