Expression for field due to magnetic monopole

AI Thread Summary
The expressions for the magnetic field due to a monopole are analogous to those for an electric charge, substituting pole strength for charge. The magnetic field generated by a monopole follows the formula p/r^2, where p represents pole strength. However, the force exerted by a magnetic pole differs from that of an electric charge, as the field of a magnetic dipole mirrors that of an electric dipole, using magnetic dipole moment instead. This distinction highlights the differences in behavior between electric and magnetic fields. Understanding these relationships is crucial in the study of electromagnetic theory.

1)It is said that the expressions for field due to a magnetic monopole is similar to field due to a electric charge except that in the former case we take pole strength in place of charge. Is it true?
i.e. Electric field due to a point charge = Q/r^2 Magnetic field due to a magnetic monopole = p/r^2
where p = pole strength,Q = charge
Is it true for force exerted by a magnetic pole at a given point?

No, the field of a magnetic dipole is the same as the field of an electric dipole except you replace the electric dipole moment \vec{p} for the magnetic dipole moment \vec{\mu}.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
