  • Describe how a magnetic field is created. Explain how the electromagnet and the solenoid work together.
In 1820, a Danish scientist named Hans Oersted discovered that a magnetic compass could be deflected from its resting position if a wire carrying electric current were placed near the compass. This deflection of the compass only occurred when current was flowing in the wire. When current was stopped, the compass returned to its resting position. Magnetic Field This graphic seems to indicate that any wire in which an electric current is flowing is surrounded by an invisible force field called a magnetic field . For this reason, any time we deal with current flowing in a circuit, we must also consider the effects of this magnetic field. We have all probably had experiences with magnets at one time or another. Magnets attract certain types of material like iron but almost nothing else. Electromagnetism The term electromagnetism is defined as the production of a magnetic field by current flowing in a conductor. We will need to understand electromagnetism in greater detail to understand how it can be used to do work.

The foundation was laid by the observation first made by Hans Christian Oersted (1777-1851), professor of natural philosophy in Copenhagen , who discovered in 2820 that a wire uniting the poles or terminal plates of a voltaic pile has the property of affecting a magnetic needle I (see Electricity 1 In the Annals of Philosophy for November 1821 is a long article entitled " Electromagnetism " by Oersted, in which he gives a detailed account of his discovery. He had his thoughts turned to it as far back as 1813, but not until the 20th of July 2820 had he actually made his discovery. He seems to have been arranging a compass needle to observe any deflections during a storm , and placed near it a platinum wire through which a galvanic current was passed. Oersted carefully ascertained that the nature of the wire itself did not influence the result but saw that it was due to the electric conflict, as he called it, round the wire; or in modern language, to the magnetic force or magnetic

Tesla Electromagnetism is the physics of the electromagnetic field: A field that exerts a force on particles that possess the property of electric charge , and it is in turn affected by the presence and motion of those particles. A changing magnetic field produces an electric field , a phenomenon known as "electromagnetic induction." This phenomenon forms the basis of operation for electrical generators , induction motors, and transformers ). Similarly, a changing electric field generates a magnetic field. A magnetic field is produced by the motion of electric charges, that is, an electric current. The magnetic field produces the magnetic force associated with magnets. Because of this interdependence of the electric and magnetic fields, it is appropriate to consider them as a single coherent entity, the electromagnetic field. The theoretical implications of electromagnetism led to development of the theory of special relativity by Albert Einstein in 1905.

Magnetic Effect Of Current Or Electromagnetism
The term "magnetic effect of current" means that "a current flowing in a wire produces a magnetic field around it". The magnetic effect of current was discovered by Oersted in 1820. Oersted found that a wire carrying a current was able to deflect a magnetic needle. Now, a magnetic needle can only be deflected by a magnetic field. Thus it was concluded that a current flowing in a wire always gives rise to a magnetic field round it. The magnetic effect of current is called electromagnetism which means that electricity produces magnetism.

    The discovery of the relationship between magnetism and electricity was, like so many other scientific discoveries, stumbled upon almost by accident. The Danish physicist Hans Christian Oersted was lecturing one day in 1820 on the possibility of electricity and magnetism being related to one another, and in the process demonstrated it conclusively by experiment in front of his whole class! By passing an electric current through a metal wire suspended above a magnetic compass, Oersted was able to produce a definite motion of the compass needle in response to the current. What began as conjecture at the start of the class session was confirmed as fact at the end. Needless to say, Oersted had to revise his lecture notes for future classes! His serendipitous discovery paved the way for a whole new branch of science: electromagnetics. Detailed experiments showed that the magnetic field produced by an electric current is always oriented perpendicular to the direction of flow. A simple method of showing this relationship is called the
