Actually, the pole of the magnetic field of the earth at the North of Earth is the "South Pole" but not the North Pole.<br /><br />As you can see in the diagram above, the compass is actually pointing away from the North pole and pointing towards the South pole or it is always pointing in the direction of the field.Sekhttp://www.blogger.com/profile/05333466968034873958noreply@blogger.comtag:blogger.com,1999:blog-5754734678634830817.post-5852486042021751112009-05-05T05:04:00.000-07:002009-05-05T05:04:00.000-07:00Sl<br /><br />referring to shreyas's question earlier. But i thought the compass pointer always points to the north no matter what? so what do you mean when you say "the pointer of the compass will be in the same direction as the field."?<br /><br />thxtHe ElIxirhttp://www.blogger.com/profile/14013298463619312144noreply@blogger.comtag:blogger.com,1999:blog-5754734678634830817.post-62092653102949756942009-02-19T08:15:00.000-08:002009-02-19T08:15:00.000-08:00Shreyas, TQ for your question.<BR/><BR/>The magnetic field is coming out from the South pole, directing towards the North pole.<BR/><BR/>Therefore, if you put a compass in a magnetic field, the pointer of the compass will be in the same direction as the field.Sekhttp://www.blogger.com/profile/05333466968034873958noreply@blogger.comtag:blogger.com,1999:blog-5754734678634830817.post-41353945285661480592009-02-19T08:07:00.000-08:002009-02-19T08:07:00.000-08:00OK, first off- Thanks. This site is really helpful, and has cleared quite a few doubts.<BR/><BR/>However, I still am a little confused.<BR/>1) Can you explain the change of the compass point direction in a bar magnet and a straight conductor? What do you mean when you say that 'it points in the direction of the field,and so it points to the north?<BR/><BR/>ThanksShreyashttp://www.blogger.com/profile/07495154825511843940noreply@blogger.comtag:blogger.com,1999:blog-5754734678634830817.post-80062956653097909472008-07-18T01:37:00.000-07:002008-07-18T01:37:00.000-07:00Visitors are welcomed to post question or give further expiation to the topic at the comment column.<BR/><BR/>The "Post Comment" window can be accessed by clicking on the "comment" hyperlink.Sekhttp://www.blogger.com/profile/05333466968034873958noreply@blogger.com
