An electric motor is a device that converts electrical energy into mechanical energy. It works by using the principle of electromagnetism, which is the interaction between electric currents and magnetic fields. There are different types of electric motors, but the basic idea is the same: a coil of wire carrying an electric current rotates inside a magnetic field, creating a force that makes the coil spin. One of the simplest electric motors is a DC motor , which runs on direct current (DC) from a battery or a power supply. A DC motor has two main parts: a rotor and a stator. The rotor is the part that spins and has a coil of wire wrapped around an iron core. The stator is the part that stays still and has a permanent magnet or an electromagnet. The coil of wire on the rotor is connected to a split ring called a commutator, which rotates with the coil and switches the direction of the current every half turn. This ensures that the coil always experiences a force in the same direc...
FOUR HIDDEN ROMAN SWORDS FOUND IN AN ISRAELI CAVE. THE SWORDS WERE PRESERVED IN AN EXCELLENT STATE. September 6, 2023/JNS
Four hidden Roman swords found in an Israeli cave The swords were preserved in an excellent state. Sejal Sharma Sejal Sharma | Sep 06, 2023 03:30 PM Four Roman swords dating back 1,900 years have been discovered in a near impregnable crevice inside a small hidden cave in Israel’s En Gedi Nature Reserve in the Judean Desert. As per the initial findings, the researchers believe that the swords were hidden by the Judean rebels after they were seized from the Roman army as booty. It was revealed from the way the swords were assembled that these kinds of swords were used regularly by the Roman soldiers stationed in Judea in the Roman period EST Sensation in the Judean Desert: a cache of four 1,900-year-old, excellently preserved Roman swords and a shafted weapon were discovered in a crevice in a cave in the ‘En Gedi Nature Reserve. It appears that the weapons were hidden by the Judean rebels, after they were seized from the Roman army as booty. “Finding a single sword is rare—so ...
