    Sia ? 6 years, 3 months ago

    A solenoid is a long circular coil containing a large number of close turns of insulated copper wire. When a electric current is passed through the solenoid, it produces magnetic field around it as shown in fig. Magnetic field produced by a current carrying solenoid is similar to the magnetic field produced by a bar magnet. As is clear from the figure, the lines enter from the left side and leave out from the right side. If we look from left side, the current appears to be passing in the coil in clockwise direction and hence it acts as a south pole according to clock rule. If the coil is viewed from right side, the current appears to be in anticlockwise direction. Hence, left-hand side face behaves as if this were a north pole. If the coil is left free, it will point South and North.
    Since the current in the turns of the solenoid flows in the same direction, the magnetic field produced by each turn of the solenoid adds up, giving a very strong resultant field inside the solenoid. Hence, a solenoid may be used in making electromagnets.

    • Menstruation: The period—the shedding of the uterine lining. Levels of estrogen and progesterone are low.
    • The follicular phase: The time between the first day of the period and ovulation. Estrogen rises as an egg prepares to be released.
    • The proliferative phase: After the period, the uterine lining builds back up again.
    • Ovulation: The release of the egg from the ovary, mid-cycle. Estrogen peaks just beforehand, and then drops shortly afterwards.
    • The luteal phase: The time between ovulation and before the start of menstruation, when the body prepares for a possible pregnancy. Progesterone is produced, peaks, and then drops.
    • The secretory phase: The uterine lining produces chemicals that will either help support an early pregnancy or will prepare the lining to break down and shed if pregnancy doesn’t occur.

    ✴️construction :- amateure coil - it is rectangular coil wound over the soft iron core. ✴️ Field magnet =these are the two concave shape magnet poles in b/w armature coil be placed. ✴️ Slip ring =these are the two metallic ring S1 nd S2 from which two ends of armature coil ate connected. ✴️ Brushes =these are two metallic plates B1 nd B2 which are connected from s1 nd s2.

    working = suppose coil is placed perpendicular to the field so, that area vector is ll to the magnetic field. if pQ moves downwards then by Fleming r8 hand rule direction of induced current is from Pto and Rto S in the coil. while in external circuit from B1 to B2. After half rotation PQ moves upward and by Fleming r8 rule direction of current in the coil is from Q to p and s to R. while in external circuit it is from B2 to B1 hence the obtain current is alternating in nature.

    1).Melting and Boiling point ●The boiling point increases as the number of carbon atom in a carbon chain. ●For the same alkyl group,the boiling points of alkyl halides decrease in the order of: RI>RBr>RCl>RF. (This is because with the increase in mass and size of halogen atom , the magnitude of vader waals forces increases) ●The boiling points decreases with the size of branching. 2).Solubility The haloalkanes are only slightly soluble in water. 3).Density The density increases with increase in the number of carbon atoms and halogen atoms a.

    Chelation therapy is the medical treatment for reducing the toxic effect of metals. Chelating agents are organic compounds that are capable of linking to metal ions to form less toxic species that are easily excreted from the body. Chelators bind metals and remove them from intracellular or extracellular spaces.
