Our science textbook says it is, but then a scientist friend said it wasn't.

I don't want to teach the wrong information to the kids!

Nickel is ferromagnetic. Usually, that means "magnetic." It isn't a particularly strong ferromagnet compared to iron or cobalt, which may be what your friend means.
The other ferromagnetic elements are dysprosim and gadolinium, neither of which are common and both have Curie temperatures below room temperature, so they're kind of useless in most cases as magnetic materials.

Is Nickel Magnetic

Almost all materials are magnetic in the following sense: A material will fall into one of three categories.
1) Paramagnetic
2) Diamagnetic
3) Ferromagnetic
Ferromagnetic is what you are talking about & only a few pure elements are ferromagnetic. Iron (Fe), Nickel (Ni), Cobalt (Co), and Gadolinium (Gd) are all ferromagnets. But like the others have said, Fe is much stronger than Ni.
A paramagnetic material is like a ferromagnet, but very much weaker. A diamagnetic material is actually repelled by a bar magnet (the opposite of paramagnetic), but the force is so weak that you'd have a tough time measuring it.
Teach your kids the whole truth even if it is a little over their heads!

Yes, Nickel is another metal that has strong magnetism besides Iron. Nevertheless, Iron is by far the strongest. I think, that those are the only two metals that has strong magnetism. Copper, gold, silver, lead, Zinc, aluminum are not magnetic.
So, your friend is wrong. You can do it yourself, Ni is a common metal, you can buy it pure. If you put a magnet close to it, it will be attracted the same way iron does, just less strongly.

Here's what Wikipedia says:
==
Nickel is one of the five ferromagnetic elements. However, the US "nickel" coin is not magnetic, because it actually is mostly copper, but old Canadian nickels minted until 1958 were.
==
So, yes, Nickel is magnetic.
You should also read about alnico, an alloy from which magnets are made:

The Nickel is ferromagnetic at high temperature but is not magnetic at low temperature.

Yes I did a science fair project on it. If I remember right, it is. You can test it out with a magnet, I think.

yes it is attracted weakly by a magnet so it is a magnetic metal.

no nickel is definitly non-magnetic , I used to work in the scrap business and sold much nickel ,

Yes it is a magnet and so is ... i forgot
