An electromagnet would have the greatest strength if its wire were wrapped around a core made of what?
iron
What effect would increasing the number of loops in a coil have on an electromagnet?
Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
Why does more coils make an electromagnet stronger?
The illustration on the HowStuffWorks website is probably the easiest to understand. As you add coils to the electromagnet you have more and more magnetic field traveling in a certain vector (depending on which way current is flowing). It's much like a lot of physics...as you add horses to a plow the force is increased. As you add coils to an electromagnet the magnetic field increases. As I said, check out this link for better understanding. http://science.howstuffworks.com/electromagnet4.htm\ A wire with an electric current passing through it, generates a magnetic field around it, this is a simple electromagnet. The strength of magnetic field generated is proportional to the amount of current. if we were to increase the number of coils the strength of the magnetic field would increase, also increasing the strength of the magnet
Striking experiment with straight sided glass?
A person can perform an experiment with a straight sided piece of glass to see if it has more strength when it is hit while it is horizontal or vertical. It has been proven that a piece of glass used in an automobile will have more strength when it is hit at an angle. This is why the windshield on a car is not straight up and down like a window would be.
What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
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.

iron
How does the number of turns affect the strength of the electromagnet?
i think it's not on the size but rather on the voltage capacity of the battery.. usually bigger batteries have higher voltages that's why we may relate it to their size, but there are some batteries despite being small in size have higher voltages. if we are comparing two batteries of different sizes but with the same voltages, maybe the question is which one will last and would sustain your magnet longer.. but in terms of power, they are the same
Can glass affect birth control?
I can't think of any way that glass would affect birth control.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
Why rupture strength is preferred to ultimate rupture strength?
Ultimate strength is used for materials that yield before breaking, like metals; rupture strength is for materials that break suddenly, like glass. Ultimate rupture strength would imply some yield strength before finally breaking and is not a preferred term for brittle materials like glass.
What are the arrangement of moving magnets and wire coil called?
electromagnet
When would an electromagnet stop working?
An electromagnet would stop working if the electrical current flow is interrupted or if the power supply is disconnected. Additionally, if the coil overheats, it can damage the insulation and cause the electromagnet to fail.
