Magnetic potentialsMagnetostaticsMaxwell's theoremPaleomagneticsSummary This study considers two well-known problems arising in the determination of the Earth's magnetic field, either from measurements of intensity alone or directions alone. Several theorems are proved here to demonstrate the uniqueness of...
How to find magnetic field between two parallel current-carrying wires? A 0.60-T magnetic field is directed perpendicular to the plane of a circular loop of radius 0.40 m. What is the magnitude of the magnetic flux through the loop?
How to Draw the Magnetic Field Around a Current-Carrying Wire Step 1:Identify the direction of the current within the wire. Step 2:Use the right-hand rule and align your right thumb with the direction of the current. Step 3:Find the direction of the magnetic field by curling the...
Hi everybody, I am doing a project in MATLAB. My project is: using the Biot-Savart law, determine the magnetic field in a round circuit. Here is the equation: The requirements are: Enter the radius of the circle (the round circuit) Divide the circle into many ...
How to Draw the Magnetic Field Lines of a Dipole Step 1:Identify the type of dipole present. Step 2:Determine the direction of the magnetic field around the dipole based on the location of the poles, by the flow of the current which produces the dipole, or the polarity. ...
The direction of magnetic field due to straight wire carrying current can be determined by right hand thumb rule. IF you grab the current carrying wire with your right hand. It such a way that thumb is in the direction of current, then the curled finge
How to find magnetic declination?Question:How to find magnetic declination?Magnetic Elements of Earth:Magnetic elements of earth at a place are the quantities which describe completely in magnitude as well as in direction , the magnetic field of earth at that place. There...

Some animals can sense the earth's magnetic field (磁场),while humans can't.This magnetic field guides a certain kind of fish when they swim a long way to a place and then back.How can this kind of fish do that?It is still a mystery.Scientists have no good answers yet. However,anim...
