The space within a current carrying solenoid is filled with magneisum having magnetic suscepitbiliy. `x=M_(g) =1.2xx10^(-5)`. What will be the percentage increase in magnetic field?
Text Solution
Verified by Experts
Magnetic field without magneisum is `B_(0)=mu_(0)H` With magnisum, `B=muH=mu_(0)(1+chi)H` `therefore % "increase" =((B)/(B_(0)-1))xx100` `" " =chi_(mg)xx100=1.2xx10^(-5)xx100=1.2xx10^(-3)`
