1. Hi everyone!
Need some help here!
What is the shape of the magnetic field around a solenoid
How can the magnetic field around a solenoid can be strengthened?

Love being a geek!

3. Go to youtube and search for mit, they have some good video demonstrations on electromagnetics.

You don't appear to be asking for help. You appear to be asking for the answer. This is contrary to the unwritten rules of the forum.

We are interested in helping people with their homework, but not by providing answers. Rather we wish to guide them towards answers, help them get past bottlenecks of comprehension, mudge their thinking in the right direction. Ultimately, if we simply provide the answer, we do the that person a disservice in two ways. They learn a fact, not a way of thinking about facts; they may come to rely on this approach.

That would be unethical.

What sort of shape do you think it has? Here are some options? Which do you think is most likely?

Sphere
Circle
Torus
Dogbone
Figure eight
Compressed figure eight
Cones, projecting axially from each end of the solenoid
Ellipsoid

Or is it a shape that is not here?

Good question? What do you think? Would you agree that the most likely thing is to make a change directly affecting the solenoid? To take a simple illustration - it doesn't seem likely that digging a hole in Alaska would strengthen a solenoid in Illinois.

So what properties does a solenoid have and what is it we do to it when we operate the solenoid? Which of these properties do you think might change the magnetic field if changed? How might we change the actions, to strengthen the field?

What have you tried so far to answer these questions? As others have reminded you, we don't do people's HW for them, but we might be able to give hints to get you unstuck. But you haven't made clear what thinking, if any, you have already put into answering these questions. So please tell us.

6. Instead of beating around the bush about homework, why not recommend that: a large iron or steel nail or bolt be found, wind about 20 feet or so of thin, insulated wire around it, connect the ends to a low voltage source, battery, see how many paperclips the electromagnet so produced will pick up, then........change some things.

(more turns of wire, less, two batteries in series, etc). Little difference exists between an electromagnet and a solenoid, really.

Did I "give away" too much, ingrates? joc
