Electromagnets | Physics cloak of hidden flasks Club
In 1825, British scientist William Sturgeon, a soft iron rod when placed into the solenoid cloak of hidden flasks of the magnetic force discovered a lot longer. The magnetic force as quickly magnetized bar on the solenoid he added. Solenoid combination with the iron core of the electromagnet was called.
Instead of a linear conductor cloak of hidden flasks current, is passed through a conductor cloak of hidden flasks wound in the form of rollers, further comprising magnetic field strength becomes large. With the number of turns of the reel (N) conductor of the current intensity (I), how much, no matter how short the length of the reel, whereas the magnetic field so intense that it would occur. (H = Ni / t) is such a conductor spool a simple electromagnet.
In this case, the magnetic force lines go from one end of the spool ends up at the other end. Thus, conductive coils, as long as current is passed through, the south pole at one end acts as the northern tip of the other acts as a magnet. Determined by the intensity of the magnetic field lines of force, violence, along the axis of the roller gets the most value. This intensity axis of the reel of magnetic permeability (larger) is placed on a rod made of a material, can be further enhanced. (B = * H) This bar electromagnet? Kernel? is called. cloak of hidden flasks Iron is one of the substances used for this purpose.
Voltage of the circuit and by increasing the number of turns on the bar magnet characterized electromagnet increases. cloak of hidden flasks In other words, cloak of hidden flasks with increasing voltage and a stronger electromagnet number of turns is obtained. Electromagnet magnetic field lines around the bar magnet is composed as follows.
Ampère cloak of hidden flasks later, when the current-carrying wire is wound into a coil, the magnetic field can be strengthened thought. Experiments showed that he was right. When current passes through the wire wound into a coil, called a solenoid coil rod that acted like a magnet.
In practice, different shapes and sizes according to the purpose of electromagnets are made. Electric door bells, door opening mechanisms, opening the electric circuit, cloak of hidden flasks the switching unit (relay), very strong magnetic field, charged particles accelerators cloak of hidden flasks where needed, are just a few of the applications that use electromagnets.
Near the magnetic field of the electromagnet is switched on any iron or steel part is energized. Stop pulling when it is closed. When you press the button of an electric bell from the current through the coil of the electromagnet pulls the metal rod. Handle pass current through the electromagnet is approached from the ignition circuit is separated and disconnected. Electromagnet releases the lever arm is pulled back by the spring, the hammer strikes the bell. Repeat circuit is completed, the electromagnet pulls the lever again, and the cycle is repeated. Thus, the constant opening and closing of the electromagnetic field, mechanical action (the hammer to hit the bell) and audio (the ring signal) is converted
To obtain a solenoid wire tightly around a pen Let's scan. Solenoid let's connect the ends of the strips to the ends of the battery. Achieved if we have the power to affect the electromagnetic compass can not take any metal will be too weak. If you use an iron rod instead of a pen or paperclip to pull pin power we obtain an electromagnet. EXPERIMENT
Yellow bars on your insulated wire. One of the ends of the wire of the power supply positive (+) pole and the other end to one end of the switches connect. Switch on the other end of the connection cable of the battery negative (-) terminal Connect to.
Key is open to the rod of iron powder'm yaklaştıral. When iron powder closer to the bar attracts iron powder. In the same way by turning the key to the iron rod of iron powder'm yaklaştıral. Bar thus does not attract iron powder. Because we have closed current. The number of windings on the rod and engaged repeat the experiment when increasing the voltage further increases cloak of hidden flasks the tensile strength of bars are shown. Study of an electric bell:
A and D are connected to buttons circuit. Circuit to be closed by the electromagnetic pulley, then touch the screws and pallet B to D, reaching the current cloak of hidden flasks cycle completes. Current flow in the electromagnet pulls the pallet and pallet mıknatıslanıp iron bar attached to the bell clapper hits.
Pressing the button turns off the telegraph transmitter and receiver going to his current passing through the electromagnet makes the iron bar magnet. The magnet pulls pallets and pallets across the strip of paper at the other end of the pen draws a line or point. Telegram instruments have been developed today. Morse code, but directly with alphabet letters cloak of hidden flasks were made by the device. cloak of hidden flasks
A simple telephone circuit with a microphone, a battery and has a headphone. Coal particles located cloak of hidden flasks in the microphone. Speaking in front of a microphone diaphragm vibrates according to the severity of the microphone. Coal particles trapped relaxation resistance and therefore increase the intensity and decrease the current. This event changes the tensile strength of the electromagnet in the earpiece.
