Why are there more thumbtacks attached in electromagnet b as compared to electromagnet a?

I'm having a lot of trouble seeing the picture that goes along with this question in the book,
so I'll have to take a wild guess based on no information.
My guess is that electromagnet 'b' has more current flowing in its wire coil than electromagnet 'a' has.
Another possibility is that the current through both coils is the same, but the coil of electromagnet 'b'
is wound with more turns of wire than the coil of electromagnet 'a' is.
It's just a guess. To be sure, I really need to see that picture.

Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
What makes an electromagnet more powerful?
more coils around the metal object, thicker wire being coiled, and more electricity going to the wire.
How do you calculate pitch using length and number of coils?
Number of coils of what? Maybe wire in an electromagnet? Please resubmit the question with more detail.
What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?
The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
Is there more ways to increase the strenghth of an electromagnet?
no
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
How does an electromagnet make the sounds you hear in headphones?
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
Why do the number of windings around an electromagnet affect the strength of and electromagnet?
This is because an electromagnet gets its magnetic force from the electrons passing through the wire, the more coils there are the more electrons passing through so the more magnetic power. Obviously this only works to an extent since you would need more voltage and so on.
Is there more than one way to increase the strength of an electromagnet?
Yes
Is there more than one way to increase the strength of electromagnet?
Yes
What is a eletromagnet produced by?
I believe that it's spelled electromagnet. An electromagnet is produced by electricity flowing through a wire wrapped around a needle 30 or more times.
How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
