We can very well feel the magnetic field around a magnet, but we can't see it. Why is that so?

Also, can we cut a portion of the field and use it?

Hi Suvankar. Welcome to Physics.SE. Shall I ask a question to you: "Then, Have you seen gravitational, electric and electromagnetic fields?" Please have a look at the wiki links. They may provide some intuitive look on the topic :-) –  Waffle's Crazy Peanut Jan 18 '13 at 15:08

You can only see things if they generate, absorb, reflect, or refract light. BTW, you can see magnetic fields by using iron filings. –  Mike Dunlavey Jan 18 '13 at 15:27
    
This is an interesting question. Too bad it was never answered. Some species of birds can see magnetic fields, after all. –  markovchain Mar 30 '13 at 4:26
