magnetic effects kisko nahi aata?????
1) a charge at rest produces electric feild only but charge in motion produces electric and magnetic feild only
2)the current flows along the direction of +ive charge and opp. to direction of -ive charge
3)In the case of pipe carrying a cuurent , M. feild reside outside only but in case of rod it resides outside and inside
4)wen a charge enters uniform M.F. , it follows a............
a)strt. line path wen B is ll to V i.e theta = 0 or 180
b)circular path wen B is perp. to V
c)helical wen B is at some arbitary angle to v
i.e theta is not = to 0 , 90 or 180
5)a proton , dutron and an alpha particle enters a uniform MF making an angle 90 to the direction of M.F. the ratio of radius of path followed by them wen....
a)they have same kinetic energy = 1:(2)^1/2 :1
b) they hav = potential diff. = 1 : root 2 : root 2
c)= momentum = 2 : 2 : 1
thank u
