A physicist works in a laboratory where the magnetic field is $2 T .$ She wears a necklace enclosing area $0.01 \mathrm{~m}^2$ in such a way that the plane of the necklace is normal to the field and is having a resistance $R=0.01 \Omega$. Because of power failure, the field decays to $1 T$ in time $10^{-3}$ seconds. Then what is the total heat produced in her necklace ? $(T=$Tesla$)$
