If the water source is removed, the farmland will randomly dehydrate and then get reverted to a dirt block. Flowing water will also manage to hydrate surrounding blocks. The crops are one continuous 'shelf', so can hold the mouse button and move as you are planting or harvesting.Ī single block of water will manage to hydrate a 9×9 square on the same y-axis height around it, giving a total of up to 80 blocks hydrated.Ī freshly tilled farmland block will get randomly hydrated when near a water block. This is a spiralled variation of the farm. (Oh, and the chest at the door is good for storing excess seeds or wheat.)

The walls of the farm serve a double purpose - keeping animals out and serving as a back wall so that harvest crops bounce back to you. The nice thing about this design is that you can elongate the design simply by repeating the middle row (the one with water in it). The tilled blocks are raised so you won't trample crops as you collect them, and the water tile in the middle ensures that all the crops are exposed to the water. There is a thread on the Minecraft Forums with various farm designs - here are two of them (credit to Hans Lemurson of the forums): Even though a large field of crops would result in the quickest growth time, this is not necessarily the most efficient method of farming as you would need to crouch to avoid the trampling of crops, and it's not easy to access each tile. Like I said, I'm not going to build a demonstration version of a railgun.Like Brant said, tilled soil will stay tilled if it has a water tile four blocks or less away. But wait! If I have 1000 amps in the rails, won't the rails also push on each other? Yes. Really, the only way to get that high of a current is with some type of capacitor bank that can be discharged very quickly.

What about 1000 amps? Yes, that might do it. Also, there is no way my power supply could get up to 100 Amps. This would increase the force to just 4 x 10 -3 N. What if I increased the current? Actually, since both the force and the magnetic field are proportional to the current, doubling the current would increase the force by a factor of 4. Since the magnetic field and the current are perpendicular, this is easy to calculate the magnitude of the force. Now if I have the same 10 amp current running through the 2 cm long cross over wire (projectile), I can use the following to calculate the force on a wire with current: If I use a distance of 2 cm and a current of 10 amps, I get a magnetic field of 2 x 10 -4 Tesla.~ r is the distance from the center of the wire. Maybe this diagram will help visualize what's going on. This magnetic field then pushes on the projectile with the current running through it to propel it out of the railgun. In between the two parallel rails, both of the magnetic fields due to the rails points in the same direction and make a stronger magnetic field. An electric current goes down one wire, across the projectile and then back down the other rail. You have two parallel rails (thus called a railgun) and a moveable projectile that is also like a wire. Putting these two ideas together, you can make a railgun. One direction is in the direction the wire swings. There are only two directions perpendicular to both of these vectors. In this example (from the video), the current is to the left and the magnetic field is upwards. What about the direction of the force? This force is perpendicular to both the direction of the current and the direction of the magnetic field. When current runs through the wire, there is a magnetic force on the wire which causes it to swing. The wire with current is near the magnet. Don't keep the wire on the battery for too long, it will get hot.

How much it moves depends on how much electric current is running through the wire (and how close the needle is to the wire).

When you connect this wire to a battery, you will see the magnetic compass needle below the wire move a little bit. Next take a wire (any conducting wire should probably work) and place the wire such that it is oriented along a North-South line over the compass. Well, you might not have a magnetic compass - but you should get one anyway (your phone won't work in a zombie apocalypse). You probably have the materials so that you can try this at home. Let's go over some of the basic principles for the railgun to operate. What about a railgun? This weapon can fire a projectile at tremendous speeds without even using an expanding gas. The shell is then launched by the expansion of exploding gun powder. This content can also be viewed on the site it originates from.Ī conventional cannon has some type of shell in a tube.
