You can open the GRD file manually if double-clicking it doesn’t result in it opening in Photoshop. To do this, choose the Gradient Tool (keyboard shortcut G) from the Tools bar. Then, at the top of Photoshop below the menus, select the color that’s showing so that the Gradient Editor opens.

The latitude and longitude lines on maps of the Earth are an important example of spherical coordinates in real life. With the r-coordinate fixed at the radius of the Earth, the two-dimensional latitude and longitude plane is used to specify the location of different places on the surface of the Earth.

Coordinates systems are often used to specify the position of a point, but they may also be used to specify the position of more complex figures such as lines, planes, circles or spheres. For example, Plücker coordinates are used to determine the position of a line in space.

We can use the coordinate plane to graph points, lines, and more.

The two axes intersect at the origin (0, 0). Points are located within the coordinate plane with pairs of coordinates called ordered pairs—like (8, 6) or (–10, 3). The first number, the x-coordinate, tells you how far you go right or left; the second number, the y-coordinate, tells you how far you go up or down.

You can do the following steps:

1. #1 click FILE tab, click Options menu from the popup menu list.
2. #2 click Advanced tab in the left section of Excel Options window, move to the Display section in the right of window.
3. #3 set the Rule units as Centimeters under Display section.

If you are working in Page Layout view (View tab, Workbook Views group, Page Layout button), you can specify a column width or row height in inches, centimeters and millimeters. The measurement unit is in inches by default. Go to File > Options > Advanced > Display > select an option from the Ruler Units list.

72 points

Put the mouse pointer over the bottom right-hand corner of the cell until it’s a black plus sign. Click and hold the left mouse button, and drag the plus sign over the cells you want to fill. And the series is filled in for you automatically using the AutoFill feature.

Cartesian coordinates are also essential tools for most applied disciplines that deal with geometry, including astronomy, physics, engineering and many more. They are the most common coordinate system used in computer graphics, computer-aided geometric design and other geometry-related data processing.

Difference Between Fleming’s Left-Hand and Right-Hand Rule

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in the direction of the the resulting magnetic force …

The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the right hand point in the direction of v, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.

Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas, as of 2011.

Iron

You can make an electromagnet stronger by doing these things:

• wrapping the coil around a piece of iron (such as an iron nail)
• adding more turns to the coil.
• increasing the current flowing through the coil.

Electromagnets have the main benefit of manipulating their magnetic pull strength – both by turning the magnet on or off and by adjusting the current. They also feature greater pull strength than permanent magnets. Some estimates place the largest electromagnet at 20 times stronger than the strongest permanent magnet.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Yes, a typical copper wire electromagnet with an iron core consumes electricity constantly which is a waste of energy that is not required by the laws of physics to maintain force. The exception is a superconductor which can be an electromagnet yet it doesn’t consume electricity once established.

The switch is built with 3 equal magnets and you will need some iron bars. It’s obviously not possible to turn off the magnetic field of a permanent magnet. They must be of the same size and strength for the magnetic fields to eventually collapse.

An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor.

There are many different ways to demagnetize a magnet. As we know, a magnet has magnetic moments inside it, i.e. the arrangement of molecules in a particular direction. When we repeatedly hammer on a magnet, it will free the magnetic dipoles inside the magnet from its ordered orientation.

This magnet just does not have enough force or Magnetic field strength to be able to pull on the actuator on a safe, you will need at minimum (as Mr locksmith has informed me) a magnet with at least 200lb pull force and that is cutting it close.

With the help of rare earth magnets, opening a safe can take just seconds. At least that is what Terry Whin-Yates of Mr. He showed that, using a rare earth magnet, one can exploit the nickel piece in this Sentry Electronic Safe to get it open without any damage.

Luckily, locksmiths are trained to work on electronic safes, along with traditional ones. Before calling in a locksmith if you notice your keypad is not turning the bolts, you can try a little troubleshooting yourself. When bolts won’t turn, it does not automatically mean the wiring is damaged or frayed.
