To determine the north magnetic field, use the figure in the direction indicated by the compass needle.
To determine the direction of the magnetic field at any point, you can use the right-hand rule. Point your thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field.
Curl your right-hand fist around the wire, with your thumb pointing in the direction of the current in the wire. Your four curled fingers point in the direction of the magnetic field that surrounds the wire.
To determine the widthwise dimension of the object, measure from side to side.
The orientation of a dipole in a magnetic field will align along the direction of the magnetic field. The north pole of the dipole will point towards the south pole of the magnetic field and vice versa, in order to minimize the potential energy of the system.
the needle should point north unless your are close to another magnetic object which could interrupt it.

By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.

A geologic survey to determine depth, amounts, and direction of ore bearing minerals.
the needle should point north unless your are close to another magnetic object which could interrupt it.
The cheap and easy way that we did in school long ago was to put the magnetic on a table, lay a sheet of paper on top, and sprinkle iron shavings on it. I don't know if that always works, but it did for our experiment. If you are looking to measure the Gauss of the magnet. I would see how much force is exerted on a steel bar and search the Internet to see if there are some simple formulas. Depending on what you're looking for, I can provide more help.
To verify the direction of the induced current in a circuit, you can use the right-hand rule. Point your right thumb in the direction of the changing magnetic field and curl your fingers. The direction your fingers curl will indicate the direction of the induced current.
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
To use the right-hand rule for determining the polarity of an electromagnet, hold your right hand with your thumb pointing in the direction of the current flow. Your fingers should curl in the direction of the magnetic field. The side of the electromagnet where your fingers point is the north pole, while the opposite side is the south pole.
Use the right hand rule. Take out your right hand, wrap your hand around the loop, your fingertips should curve to the direction of the wiring, that is, the current should be coming out from your wrist to your fingertip, and the direction of your thumb is the magnetic fieled produced. The thumb is N, and the other is S.Alternative AnswerThe left-hand 'grip' rule for determining the magnetic polarity of an electromagnet applies for ELECTRON FLOW current direction -i.e. current flow from negative to positive. Grasp the electromagnet with the curl of the fingers pointing in the same direction as the electron flow current, and the thumb will indicate the north pole end of the electromagnet.For CONVENTIONAL FLOW (positive to negative), we use the right-hand 'grip' rule instead.
