Question

describe an activity to find magnetic field due to straight wire carrying current​

Answer 1

Answer:

Ampere's right hand grip rule

$\mathtt{Take\: along \: a\: straight\: conductor} \\ \mathtt{and\: hold\: in\: your\: right\: hand \:grip \:as} \\ \mathtt{ shown\: in \:figure \:(10.7) . \:If \:the} \\ \mathtt{direction\: of\: the \:indicate \:the} \\ \mathtt{ \:direction\: of\: current\: in\: the\: conduct} \\ \mathtt{ \:the \:direction\: in\: which\: the \:fingers} \\ \mathtt{\:are\: curled\: around\: the \:conducted\: to} \\\mathtt{ \:have \:of it, \:indicates\: the\: direction} \\ \mathtt{\: of\: the \:magnetic \:field \:produced} \\ \mathtt{\:by\: the \:current \:carrying \:conductor.} \\\mathtt{This \:is\: ampere's\: right\: hand\:<strong><em> </em></strong>rule.}$
